From what i saw they put the bar in the proper place for Colt.....Matt, sorry you can't drive this. Hey, you asked. Maybe fly out of seat or something😂
I just finished installing one of their cages in my 2000 topless XJ, it fit perfectly, I just added a few gussets. They shipped it all the way to Michigan. Cool to see their shop.
I have to thank Matt and chubby chaser lol the tip about putting the diff on the axle shaft inside the wheels to torque ring gear bolts saved me a lot of headache today
Eric and Janna are fantastic folks operating a great family run business. Great service and incredible knowledge. I consider myself lucky to have them as friends.
I took a look at the ZJ cage after you posted on IG. Looks like a grate option if I ever get to that point with my jeep. Also as someone that is 6'3" me seat is always somewhat reclined and slid all the way back in anything but a full-sized truck.
6'7" here. I actually own a (very compact) Alfa Romeo GTV6. I have a racing seat, a shell with a bit of padding, to get low enough to clear the roof. I also extended the steering 3.5" to clear my knees. It's quite comfortable now, although I do get comments from people when I get out at gas stations and other busy spots. 😁
You are definitely correct on the seat angle for taller people. I am 6'5" and got a ZJ set up for a shorter person and had to mod the cage behind the seats like you did. Great content as usual from you guys and I can't wait to see the Rats Nest XJ hit the trail.
Only 5'9 but my buddy was 6'3 when I had my 69' Mini. He hated it till I removed the front seat. My other mate is 6'5 and his driver seat is all the way back and reclined in his Mazda 929 Coupe , he uses the back driver side window to look out. Too funny seeing really tall guys step out of small cars.
My two cents. You're both right to some extent, but only anchoring the harness below the level of your shoulder will hold you down in the seat. However, both straight out or down will hold your upper torso from moving forward. Critical that you have both, but the bottom line is it needs to be customized for the person who will most frequently drive it and their driving position, otherwise it will be neither comfortable nor effective.
SFI Foundation has a "SEATBELT INSTALLATION GUIDE FOR UPRIGHT SEATING" .pdf which is pretty easy to find online. According to that, for any seat recline angle up to 25deg from vertical, shoulder belts should be 0 to -20deg below the top of the shoulders, with -10deg as optimum.
I’m a RUclipsr that has no idea about your seatbelt angle. So I’m going to wait until your done and then tell you you did it wrong, because that’s what people do on RUclips . Keep doing what you do stay safe on the trails
Love the Jeep Bar!!! That is Awesome!!! The XJ is coming along nicely!!! I’ve got a 98 4Dr might have to order one of those cages! I’m 6’2 and I sit a angle like you said, so I’m curious to know the angles you end up using! Make sure to add that info in, please! Nice series of videos!!! I think the XJ is going to be a Awesome Off-road Rig! I Love em myself!!! Especially with a 4.0!!! Hard to beat for the money!!!
Impact race products has a great illustration of how the shoulder harness should be mounted. +- 5 degrees from your shoulder height regardless of your lean angle.
For race cars with primarily head on collision protection in mind that is absolutely correct. In Jeeps however harnesses are for ejection protection not front impact at high speed protection. Alot of off road, and jumping vehicles are set up for cresting and landing forces instead to minimize injury due to the spine being compressed by torso weight on landings and the shoulders being pulled down when cresting. The seat being reclined allows the back to absorb torso weight on landing and the chest to absorb pull down forces at crest.
Awesome video as always!!! That might possibly be the cage we go with for our XJ for our channel!!!! Rats nest is coming together nicely. Keep up the awesome job!!!
Nice idea. Would it be best to paint those roll bar tubes 90% before welding them in ? I agree on the buy it made idea. Those shop have already taken the time to measure and design the best outcome not to mention you are not spending 4 weeks of your own time doing trial and error bending, welding and so forth.
For belts in race cars it's 'preferred' -10° not seat angle. But max seat angle is also part of a safe racecar setup and usually no more than -25°. Reason: In a forward impact, where the most speed is typicaly achievable, your body mass pushes forward with a lot of energy. That energy loads the shoulders and waist belts. The waist belt being mid body catches not just your legs energy but also becomes responsible for maintaining a solid lower mounting point for the Shoulder Straps. The shoulder strap energy is distributed on 3 points (a triangle) the belt mount, the shoulder wrap over point, and the rear mount. That triangle being out of square from the bodys direction of travel before the stop is what becomes dangerous. In ideal conditions the torso and heads energy becomes focused on the upper chest area of the straps, this is why the rear mount is just under shoulder height. In a race car the seats incline angle would be set and the shoulder strap angle would be calculated based on the height and weight of the drive so that the waist belt catches the appropriate portion of the torso energy. Basically making sure the driver doesn't have too much 'slip under' or 'buckle over' effect. The real spine crunch comes when the upper focus point of the energy becomes higher than the rear mount height. That energy will pull itself down to level out with the rear mount point, since your shoulders are under the strap that wants to move down they will also move down. If the amount of down they want to move is more than the length of you spine... game over. All that said, that applies to race cars, Jeeps aren't race cars. In a Jeep your most frequent body weight e energy is upward and downward as we bounce down the trail and over obstacles. Colt kinda eluded to it but gave the tall guy cop-out. The reason to lay the seat back in Jeeps, and vehicles that jump as well, is so that when stopping on the way down your spine is more parallel with the direction of momentum and your back will take some of the torso load. The down side to this approach is that if you are going fast forward and have a collision your straps will force you down into the seat due to the body sliding down the angle of the shoulder straps and into the butt area of the seat with alot of energy. With that in mind think back to the racecar scenario for the upward stops. If your shoulders are trying to move up and you have a rear strap that's parallel with the top of your shoulders all of the momentum stopping is going to be on the top of your shoulders. Angling the seat back and calling °90 off of it as our new 'level' and then mounting at -10° from that new 'level' moves more of the energy of cresting pull downs to the chest. The primary purpose of harnesses in our Jeeps is to prevent ejection. I feel that the leaned back with 90° straps method is acceptable. I also saw they have air ride bases for Jet Boats due to the force of their downward impacts, would be super cushiony with one of them and a nice Susspension Seat. One more side note. Belts to B piller bar not the back. In a bad accident things bend, you want to minimize the ability of the seat and attachment points to change locations relative to eachother.
I'm 6'1" and I can't drive any vehicle without the seat reclined a little bit. I'm planning on doing a cage in my TJ this year and I'm having the same problem. There's a ton of different opinions on where the harness bar should go.
Matt is correct according to Simpson: Anchor shoulder straps at point zero to 10 degrees below the top of the shoulder. Note: Preferred mount is as close to shoulder as possible
You gotta have tilt in the for head room. I had a 92 toyota extended cab pickup I moved my seat six inches back from factory , it makes me feel like Bubba Smith in police academy lol.
I own a tj but really miss having a cheerokee I had to sale mine because it just kept having issues I put two motors in it. But sold all parts now the tj.
From what I’ve seen, watching drag racing and road racing cars being caged, they put the belt bar straight back, level with the to[ of your shoulders. The belts are tightened so level with your shoulders will still hold you down in a rollover.
Call the NHRA and ask tech services. They can tell you the height below the drivers shoulder. Above the shoulders makes it ready easy to whack your head on the roof.
KOH has high speed desert racing, they will have 'racecar' style rules. By 'racecar' style I mean focused on frontal impact energy absorption. In our Jeeps we are using harnesses for ejection prevention. The important thing is that the rear belt is no more than -20 diffrent than the seat back (-10 preferred) so that bet body is held securely in the seat. For slow offroad and jumping vehicles the seat is typically reclined to put the body in a better position to absorb the cresting forces on the chest instead of the top of the shoulders and distribute the landing energy of the torso to the back instead of the butt.
I am not sure of exact placement of harness bars. Just going to note at 6'3"ish with a 30" inseam. I had to have my seat raiser moded heavily to get my head inside the factory roll bar in 1995 YJ. In Hondas and small cars I would kinda lay down to drive. My Civic i basically sat in the back seat to drive. One of my favorite things about Jeep is sitting upright.
Regarding your seat belts, Isn't there certain rules to follow and measurements when building a cage for a race car that needs to be inspected? I would try consulting a rule book for drag racing or road racing or some sort of organization that requires a roll cage and see if there's a certain way they want the harness bar installed. I think that would be a good way to find a safe method. I know I've answered a couple roll cage questions I've had in the past by consulting NHRA rules or something similar. I know there's different requirements for different types of racing but I think it would be a good source to consult.
Hmmm I would think that rule is based on the assumption of front on collision, however I never thought of the lean. Ether way I'm not going to sleep tonight, thanks lol
I can't drive sitting straight up, but a lot I know sit back, if the belt is straight behind you allows movement in the seat, if it's lower it will prevent movement?anyway all the best to you all and your loved ones
I lean way back, probably more like 25⁰. I'm 6'3". Don't the belt manufacturers have a recommended placement/angle for the belt based on the slots in the seat for 5 point harnesses?
Bar and the shoulder straps has to be level w/occupants shoulders. To high it won't hold you down, to low...spine compression, ouch! Get a copy of the most recent NHRA rulebook you can, that's all per SFI
The seat belt mounting should be a little lower than your shoulders that way when you do flip upside down it's pulling down on you basically which would be inverted of course being upside down. If you go straight that's fine for impacts and everything else but upside down if it's already pulled down on you a little bit when you go upside down there's less deflection
What color is the jeep bar, I love the color?? Both of ya'll have done enough seat harness installations, put it where its comfortable for you and not pulling down on your shoulders 😉!!! ✌🏻
Quit asking internet experts. What do race sanctioning bodies require? But when it comes to vehicles that may have occupants of significant height variations you should be doing multiple shoulder harness bars and seats that can handle/have more than one option for belt position. The best is always to set it up specifically for a given individual. There are no general rules of thumb. In this case I would be looking at doing three shoulder harness bars. Remember to keep the belts a short as possible. The longer the belt the more stretch there will be.
I've been looking at the DandCextreme cage and the XO fab hybrid cage. What cage do you recomend? Im kind of leaning towards the hybrid cage to free up interior space.
Seems to me that you would want some downward force from the shoulder belts to hold you in your seat in the event of a roll over, at least that's how I was told to do it.🤓
Look at your TWO mounting points of your belts... harness bar and floor. In an impact the forces try to straighten the belt between those two points. The angle of the seat doesn't have much bearing. I would mount the harness bar higher than you think vs lower. I think you are over thinking the situation anyway. Just mount it a little higher than your shoulders.
All I know is I drove a Jeep simply because , Jeep drivers go deeper in the bush ....just like compound bow users have deeper penatration ... And breaks are for p$##ys because it only hurts when the bone shows . Keep on making the video's !
most people sit at an angle! not everyone sets upright. the angle will not change the further back you go (longer line). If you move the point position in the back then the angle will change?? Head liner going back in? haha
11:48 Breaking your back is more profound than you think, Colt. Ask me how I know, 30 years after being paralyzed from chest down. Trust me when I say you don't want that challenge.
The racecar sanctioning bodies have harness mounting specs, developed over dozens and dozens of high-speed and low speed crashes. NHRA, NASCAR, etc. Use that... do not use internet opinion.... for anything.
Matt knows what's up. I understand his wording.
From what i saw they put the bar in the proper place for Colt.....Matt, sorry you can't drive this.
Hey, you asked.
Maybe fly out of seat or something😂
I just finished installing one of their cages in my 2000 topless XJ, it fit perfectly, I just added a few gussets. They shipped it all the way to Michigan. Cool to see their shop.
BOTH Colt and Matt are right here. Simply merge the 2 thoughts and it's perfect.
Yes! Some love for the WJ community! A roll cage would be sweet!
I have to thank Matt and chubby chaser lol the tip about putting the diff on the axle shaft inside the wheels to torque ring gear bolts saved me a lot of headache today
What an awesome business. I could hang out there for days just checking out the old rigs!
Eric and Janna are fantastic folks operating a great family run business. Great service and incredible knowledge.

Very good to see you guys back at it and getting your Jeep in shape, thanks for the video and keep up the good work 👍☮️

Awesome Video Colt! Excited about the ZJ Cage from D and C Extreme!! Starting to save my dollars now for a cage for my Grand Cherokee! Thanks Colt!
Right on!
I looked up and used NASCAR specs on harness for mine. May be overkill for off road but if it’s good enough for 200+ it good enough for me.
that jeep bar is legend!
I’m a RUclipsr that has no idea about your seatbelt angle. So I’m going to wait until your done and then tell you you did it wrong, because that’s what people do on RUclips . Keep doing what you do stay safe on the trails
If i was asking someone to work on a XJ w/me....
Matt would be the first i would call2😄👍
Love the Jeep Bar!!! That is Awesome!!! The XJ is coming along nicely!!! I’ve got a 98 4Dr might have to order one of those cages! I’m 6’2 and I sit a angle like you said, so I’m curious to know the angles you end up using! Make sure to add that info in, please! Nice series of videos!!! I think the XJ is going to be a Awesome Off-road Rig! I Love em myself!!! Especially with a 4.0!!! Hard to beat for the money!!!
I'm surprised Madeline does not have safety glasses on, safety 1st
Nice to see Matt there helping you 👍
ZJ gang!!🤘🇺🇲
Great video! I'm definitely planning on calling these guys for my cage
He's right about the seat back. Being a taller person really sucks sometimes. Especially when riding in a midsized vehicle.

The seat being reclined allows the back to absorb torso weight on landing and the chest to absorb pull down forces at crest.
Also, for us fluffy fellers, we need that seat lean so we aren't feeling like we should propose marriage to the steering wheel.
Awesome video as always!!! That might possibly be the cage we go with for our XJ for our channel!!!! Rats nest is coming together nicely. Keep up the awesome job!!!
Man that’s some big exciting news! As someone who daily drives a WJ on 33‘s I’ve never needed a roll cage but I think I might need one 😂😂🤙🏻👌🏻
ol mat is a pretty good hand to have around
Nice idea. Would it be best to paint those roll bar tubes 90% before welding them in ?
I agree on the buy it made idea. Those shop have already taken the time to measure and design the best outcome not to mention you are not spending 4 weeks of your own time doing trial and error bending, welding and so forth.
I understood what you were saying before you drew it out on how the angle depends on how far back it goes.
I've always heard the description, "rust bucket," this is first one I've ever actually seen. Man you are a glutton for punishment.
I understand the 6'1 6'2 issue, but think Matt has the way I would mount it!!! As long as ur safe is whole issue!!!!!!
I think Matt is correct on the angle changing.
For belts in race cars it's 'preferred' -10° not seat angle. But max seat angle is also part of a safe racecar setup and usually no more than -25°.

I just ordered one for my 87 XJ!!
PREACH COLT! I am 6 5 and you are correct
Mat is nuts
Matt is correct according to Simpson:
Anchor shoulder straps at point zero to 10 degrees below the top of the shoulder. Note: Preferred mount is as close to shoulder as possible
You gotta have tilt in the for head room. I had a 92 toyota extended cab pickup I moved my seat six inches back from factory , it makes me feel like Bubba Smith in police academy lol.
I am 6'2" and I know exactly what you are talking about with the seat recline.
Great episode Colt n Matt I learned allot today 👍🏾
I own a tj but really miss having a cheerokee I had to sale mine because it just kept having issues I put two motors in it. But sold all parts now the tj.
idk ask Tim Cameron lol his seat looks to be leanin back a ways. Dennis Anderson's take would be interesting too.
I vote for whatever is comfortable. I am not 6 2 but I sit with my seat back some
You should take a trip to Dallas Texas to meet Dennis Collins and see what he does with jeeps
Awesome video! I'm going check d&c for my zj! Keep up!
On my build im making my own seat, mounts and rollcage. Im doing a 5 point harness on an adjustable bracket.
From what I’ve seen, watching drag racing and road racing cars being caged, they put the belt bar straight back, level with the to[ of your shoulders. The belts are tightened so level with your shoulders will still hold you down in a rollover.
Agreed👍
You want it level w/ top of your shoulders so it doesn't crush your spine in a collision or what not.
Call the NHRA and ask tech services. They can tell you the height below the drivers shoulder. Above the shoulders makes it ready easy to whack your head on the roof.
Thats why most new cars have adjustable upper belt mount.
Look up belt mounts in the rules for KOH. I’m sure they have an approved range for shoulder - belt angle.
KOH has high speed desert racing, they will have 'racecar' style rules.
By 'racecar' style I mean focused on frontal impact energy absorption. In our Jeeps we are using harnesses for ejection prevention. The important thing is that the rear belt is no more than -20 diffrent than the seat back (-10 preferred) so that bet body is held securely in the seat.
For slow offroad and jumping vehicles the seat is typically reclined to put the body in a better position to absorb the cresting forces on the chest instead of the top of the shoulders and distribute the landing energy of the torso to the back instead of the butt.
So bolt your seat 💺 in and then take a musermeant to decide witch works best for the person that's driving.
I miss my first cherokee
Put the driver set in and make it right for you and/or put one of those slides in that you can raise and lower the set belt at the shoulder🤔
I am not sure of exact placement of harness bars. Just going to note at 6'3"ish with a 30" inseam. I had to have my seat raiser moded heavily to get my head inside the factory roll bar in 1995 YJ.

Sooo.. can I just send you this mint XJ I just bought from Az so you guys can build it for me???
I can't drive sitting straight up, but a lot I know sit back, if the belt is straight behind you allows movement in the seat, if it's lower it will prevent movement?anyway all the best to you all and your loved ones
Bought a D&C cage for my XJ. Not installed just yet though.
I need a WJ roll cage.. I have questions though for install
I lean way back, probably more like 25⁰. I'm 6'3". Don't the belt manufacturers have a recommended placement/angle for the belt based on the slots in the seat for 5 point harnesses?
My two cents on the seat-belt, a traditional seat-belt has a set angle. I would measure that angle before installing.
regular seat belts are different than a harness.
Tillman gloves! Everybody uses them!
ALL I got on the subject of seat belt placement is "home is where you make it". Ain't that right Joe Dirt? Dang Man
Bar and the shoulder straps has to be level w/occupants shoulders.
To high it won't hold you down, to low...spine compression, ouch!
Get a copy of the most recent NHRA rulebook you can, that's all per SFI
The seat belt mounting should be a little lower than your shoulders that way when you do flip upside down it's pulling down on you basically which would be inverted of course being upside down. If you go straight that's fine for impacts and everything else but upside down if it's already pulled down on you a little bit when you go upside down there's less deflection
Just not so much that it's going to squish you when you hit a head on impact
What color is the jeep bar, I love the color?? Both of ya'll have done enough seat harness installations, put it where its comfortable for you and not pulling down on your shoulders 😉!!! ✌🏻
the force of a frontal impact isnt gonna care what angle your seat is at
I wonder how much time was spent debating. Hilarious!
Quit asking internet experts. What do race sanctioning bodies require? But when it comes to vehicles that may have occupants of significant height variations you should be doing multiple shoulder harness bars and seats that can handle/have more than one option for belt position. The best is always to set it up specifically for a given individual. There are no general rules of thumb. In this case I would be looking at doing three shoulder harness bars. Remember to keep the belts a short as possible. The longer the belt the more stretch there will be.
I've been looking at the DandCextreme cage and the XO fab hybrid cage. What cage do you recomend? Im kind of leaning towards the hybrid cage to free up interior space.
matt's got it right..
but. .. let me make them belts out of yankum ropes.. then no spine crushing lol
The bar must be installed within four inches of the driver’s shoulders vertically, but not above them.
Mount level to shoulders to 4" below
New subscriber here, 👍
Racing seats and a 4 or 5 point harness. End of seatbelt mounting discussion
Seems to me that you would want some downward force from the shoulder belts to hold you in your seat in the event of a roll over, at least that's how I was told to do it.🤓
WJ cage please!
I sit at 10^ or more at 6’4” in my fj40 or my Ram 1500
Look at your TWO mounting points of your belts... harness bar and floor. In an impact the forces try to straighten the belt between those two points. The angle of the seat doesn't have much bearing. I would mount the harness bar higher than you think vs lower. I think you are over thinking the situation anyway. Just mount it a little higher than your shoulders.
Roughly how much weight does this cage add?
Talk to some race car people at Black hills speedway about seatbelts.
Hey colt can thy do 1a roll cage for xk commander
All I know is I drove a Jeep simply because , Jeep drivers go deeper in the bush ....just like compound bow users have deeper penatration ... And breaks are for p$##ys because it only hurts when the bone shows . Keep on making the video's !
I would look for seatbelt standards on Nhra or Nascar rules
0 degrees from level, your seating angle doesn't matter. Make it level.
If I pickup one of those will you n Matt come NY to help me put it in my XJ
Probably not, but we'd be there in spirit😎👍
most people sit at an angle! not everyone sets upright. the angle will not change the further back you go (longer line). If you move the point position in the back then the angle will change?? Head liner going back in? haha
Yes, plan is to reinstall the interior👍
My opinion is the angle is irrelevant as long as the bar is a little below the belt holes in your seat or a few inches below your shoulder line.
General rule is you don't want the belts to pull down on your back.
tell madeline i said hi. she seems nice lol
11:48 Breaking your back is more profound than you think, Colt. Ask me how I know, 30 years after being paralyzed from chest down. Trust me when I say you don't want that challenge.

wait i though it was " damn it I cut it twice and it was still too short"
It's zero degrees whether your seat is straight up or your seat is leaning back a few degrees. Zero degrees.
