- An aftermarket suspension to fit larger tires used to mean compromised suspension geometry and ride quality, but that doesn’t have to be the case anymore. Our 2006 Jeep Wrangler Unlimited rides and handles better than stock on 37-inch Nitto Trail Grapplers, and it does so without a long arm suspension. Long arms are a common upgrade on TJ Wranglers that allow the suspension arms to travel in a shallower arc for a given range of motion at the axle. The factory lower control arms are only 16-inches long, an issue that Jeep addressed with the JK and its 23.5-inch-long lower control arms. The factory arms are stamped steel with rubber bushings, they were all upgraded to JKS Manufacturing control arms with Flex Joints and heavy wall tubing. These arms are also adjustable to allow you to set the pinion angles and front caster.

Short control arms are fine at the factory ride height, it is only as the angle increases that they become problematic. Since this Jeep has an American Expedition Vehicles Highline kit, the 37-inch Nitto Trail Grapplers fit with only a 2.5-inch lift using Skyjacker coils and King remote reservoir shocks. The shocks have been custom valved for the Jeep by Samco Fabrication to improve the ride quality. More recently, SDI E-Clik reservoirs were added that use an inertial measurement unit that takes readings 250 times a second and adjusts the compression damping at each corner based on input parameters such as pitch, roll, acceleration, and braking. The end result is a smooth, controlled ride on the street that has plenty of articulation on the trail.

Wish AEV continued the highline fenders. I want a set.
Can easily make them
@@jackbower8671 is there a company that is making the model?
Make your own. Chris durnham motorsports have a highline fiberglass hood.
@@rcmike09 Save your money and chop down your hood
Not enough pictures of the track bar setup
Great vid with accurate info regarding geometry and shock valving.. I'm sure that's a NICE TJ!
Omg. Your LJ is my dream jeep. Always loved it. Great Video
Would love to get more information on how you do the track bar and drag link and parts used thanks
Quality info, Harry.
I'm making choices with my TJ build according to some of your findings with your LJ.
Your presentation on the eClik shock is warranting more consideration by me.
Thanks for sharing!

Great video, Harry. One thing I'll throw in here is that I am always an advocate for stiff shocks when rockcrawling. Going way back to when Rancho 9000's first came out and were the bee's knees, I've always used adjustable shocks. Currently I have Icons on my JTRD (in part because nobody at SDI would get back to my inquiries regarding their eClik shocks. Oh well.) On the street, I usually like to keep the shocks around the middle of their firmness range, unless I am hauling a load in which case I firm them up accordingly. When I tow a heavy trailer, the rears are set all the way stiff to help control all that additional sprung weight and minimize sway. If I'm bombing across desert 2-tracks at maximum speed, I'll also set the shocks all the way stiff to help prevent bottoming out, but I understand that like your LJ, I'm not driving a trophy truck, so I usually like to back off on the throttle and enjoy a more relaxed drive, so I'll set the shocks near the soft end of the scale and let the suspension eat. If I'm putting a lot of miles on "nuisance rocks" like what you find on the Deer Valley trail, I'll set them all the way soft and just mush my way over the rocks like a marshmallow. But if I'm doing some actual rockcrawling like on the Rubicon, I set the shocks all the way firm, which is the opposite of what most people recommend. I've tried all different settings, and the reason I like them firm is because they take all the bounce, all the head-toss, all the excessive movement out of the sprung weight. I'm not moving fast enough while rockcrawling to feel any ride quality difference with the shocks so stiff, but boy does the vehicle stay planted to the terrain. This is particularly beneficial when off-camber or doing large drop-offs where I'm approaching the tipping point with the center of gravity. Soft shocks allow a lot of wallowing that could result in the vehicle dumping itself onto its side, but with stiff shocks all excess motion is controlled and the vehicle just sticks to the terrain like velcro. Since you have such quick and easy on-the-fly adjustment from in the cab, give it a try and see if you agree with my findings about stiff versus soft shocks in the rocks.
That makes sense to me. In general I like soft springs and a lot of shock damping.
We have an ‘04 Rubicon with a 6” Nth Degree long arm kit on ORO AirRock kit. We also just picked up a 2006 LJ Rubicon and I would sell my left kidney to get my hands on a Nth Degree lift kit for it. Such a good kit.
Great information! You and Ali have the best videos!
Thank you so much!
100% you do. Great content. As a suspension guru as well you nailed every point. Great job and now I’m buying that active ride set up for my off road customers.
Good information.
Summary: Harry has a built LJ with components that are no available;( on a Jeep that’s worth more than a JL!
Easily
Hey Harry, great video! Do you have any more info on your track bar bracket would love to see an up close or short video on this?
Super awesome video, I love the information. I installed coilovers on all 4 corners on my jku and air bumps on the front axle. I haven't installed the rear air bumps or tuned the shocks yet, but it is really awesome so far.
I love this look 😍
Hi can you post a lynk for the 2.5 springs. Also will it work without having a short arm kit
Great content and well edited and delivered. You must be a professional. 😉
Good vid eh! 👌🏻
Makes me wonder if I should replace my 5" Teraflex coil springs for the duel rate Sjyjacker.
I was previously running Teraflex coils and I feel that the Skyjacker coils ride better.
Harry, what are you using for ball joints?
They look like a hybrid ball joint with an adjustable king pin cap.
They are from Skyjacker. Super burly!
Awesome video, when you drilled out the front lower control arm mounts for the geo correction did you do anything with the uppers?
I did not. There really isn’t enough material there to lower them so they are still in the factory locations.
@@HarrySituations I guess when you only lower the front bottoms an inch it doesn't counter react. I've geo corrected my rear short arms 3" and it's great, I'm thinking about doing the front lowers an inch now. Thanks
crazy to think that in some countries this build would be illegal. half of the fun with offroading is modifying and outfitting the vehicle to your wants/needs and you cant really get there unless you're mostly free to do as you please. some countries move that regulation needle too far and we'd never get builds or ideas like this.
Everything I own goes down the freeway great but when you do things at home there definitely is a wide variety of quality and safety. I can see why some countries want to limit that.
All borderline commie countries that have their citizens by the balls
In Italy any modification you can possibly think of is illegal. You cannot even substitute the engine with the exact same engine model unless the vehicle pass an inspection and a lot of paper works is done
@Harry Situations think the SDI E-Clik Active Suspension would work the the Jeep Gladiator Mojave Fox shocks, and would it be able to soften up the shocks for highway?
Unfortunately not since the Mojave shocks have piggyback reservoirs without a hose that would allow them to be replaced. The Mojave shocks are very good though, Accutune could revalve them for you to meet your needs. I had them do some shocks for my Ram recently and I was really pleased with the results and how quickly they were able to revalve the shocks.
We do have the application specific for the JT! But Harry is 100% correct, piggyback shocks would prevent us from being able to adapt the Mojave's Fox shocks.
Tire pressure is the BIG one people get wrong.
Can you redrill the LCA mounts lower without changing the mounts on the uppers? Does this not interfere with Anti-squat etc? I'm really looking to improve the ride on my TJ with 3.5" RE lift and Bilsteins. Have adjustable arms all round so I can dial the pinion angle back if necessary.
The uppers don’t have much extra space to relocate them so I did not go through the effort. It does change the anti-squat but I find more separation to improve it, not degrade it.
@@HarrySituations thanks for the info! Definitely going to try this although I think my ride issues are more Bilstein 5100 related 😂🤦♂️
@@TractorStu they are good shocks but the ability to custom valve shocks is really nice (although expensive...)
Did you use custom tracbars front and rear when you moved the racket outside the frame and used a bushing instead of the ball joint mount or does the JKS bar have the length to extend out further? I already have the JKS adj. front and rear.
It did not fit afterwards. In addition to being too short it also have the wrong type of end (tie rod style versus a bushing). I used JKS’s DIY track bar.

@@HarrySituations ah a DIY ok I missed that part in the vid. TY for responding!
What do you run your tire pressure at for freeway driving? I’m assuming you have 35” tires.
They are 37” Nitto Trail Grapplers. I run them at 30 psi on the street, 15 psi in the dirt, and 10 psi in the rocks.
I used to be heavy into off roading, spent over $100k . And can tell you DO NOT get into off roading .it will only make you poor. Get a decent pickup truck or suv and get a dirt bike, dual sport bike, or rokon 2x2 awd bike. You will save yourself many thousands of dollars and save from grief, break downs, towing costs, repair costs
What would the cost of all these upgrades run? 10k+?
Yeah probably altogether. I’ve made them incrementally over the years, but probably $2k for shocks, another $2500 for the E-Click reservoirs, $2k for control arms, $1500 for the ACOS air bumps. It adds up quickly!
Harry, what seats do you have in your LJ?
I just have the stock seats. I would love Mastercrafts or PRPs but can’t justify them since the stock seats are still in great shape.
What fender flares are these?
They are from American Expedition Vehicles.
What transmission t case and engine skids
They are from Teraflex.
Was the sdi eclick a sponsor ?
Yeah this is a new kit. I drove down to their place and they provided the parts for the installation.
Why can’t jeeps come this way?
What do all those modifications cost vs the benefits?
Great question! I find for most off-road modifications the relationship between cost and benefit isn’t linear. You could probably spend half as much and have a ride that is 80% as good. I’d start with shocks, then springs, then track bars, then control arms, then air bumps in that order.
@@HarrySituations I don't have any issues with my lifted tj. So I think I will pass on all that fancy stuff. Keep it simple less to go wrong on road and on the trails.
@@themechanic4409 sounds like you have got it all figured out. 👍
You instead made my Jeep stop working and it is beyond repair.
To much for my tj
How to make your Jeep handle great.
Step 1. Start with the unicorn of Jeeps.
Step 2. Find unicorn Jeep that has amazing discontinued aftermarket parts already installed.
Step 3. Spend $10k in additional suspension parts.
Step 4. Make RUclips video.
😂😂😂
Not sure anything can make a tj lj ride great. And too much focus on the sdi trinkets that are not needed. Otherwise good job.
You didn’t find that SDI shocks made your Jeep ride better when you used them?
Make your Wrangler ride great. Buy a 4Runner. 😁
I had a 4Runner and I did many of the same modifications (big shocks, air bumps, control arms) to make it ride great.
@@HarrySituations yeah no short wheel base solid axle is going to be comfortable on trails especially at anything over 10 mph.
You want comfort 4th gen 4Runner stock xreas suspension 34-in tires 16 to 20 psi. 40 to 50 mph over a washboard roads and rough trails feels like a Cadillac on a Sunday drive.
@@andreinvictoria my LJ has the same wheelbase as a 4Runner and I assure you it has no problem going over 10 mph in the rough. Again, I’ve had both and have upgraded both.
All right fair enough. But I would point your attention to the fact that there are no solid axle prerunners. The same way there are no independent suspension Rock bouncers. Each has their strengths. If you want to piss into the wind and tell me you don't get wet more power to ya. 👍
@@andreinvictoria *Giggles in that entire King of the Hammers class that runs solid axles and does high speed desert running*
Obviously in general ifs is better for going fast, just like in general solid axles are better for the rocks, but pretending like making those two systems do similar things doesn't cost an equally obscene amount of money is absurd. With $10,000 of suspension work I can make a Tacoma jump or a Jeep lol. The principles for making it happen are very different, and it's nowhere near as simple as "my 4Runner will always ride better than a Jeep" lol.
On another note, I know plenty of short wheelbase solid axle vehicles that ride great at slow to medium speeds using suspension technology such as ORI struts, or higher end shocks with proper valving. It's not a question of if they can do it, it's a question is if you want a short wheelbase vehicle in general going fast through actual hard stuff. I definitely don't, ifs or solid axles, I'm not racing a 95 inch wheelbase at 60 through whoops thanks.
Great Video, but it has just been banded from the all Jeep Wrangler TJ Forums by Currie and Blaine Johnson fanboies.
Buy a Bronco.
I’ve spent a fair amount of time in the new Bronco and they are definitely nice. This Jeep is paid for though and I’m not really looking for a car payment.
@@HarrySituations I don't blame you a bit. I've always liked wranglers and 20 years ago, I sold Chrysler, Dodge, Jeep, but for whatever reason I never bought a wrangler. We looked at both and just liked the Bronco better.
@@monnet74 I don’t blame you, the Bronco is pretty nice! It wouldn’t hurt my feelings to have that power train in my Jeep.
@@monnet74 should've bought a TJ or TJ unlimited .... Arguably and objectively the best American off vehicle off all time and the Goat of all jeeps... Up there right next to a Mercedes unimog and Toyota land cruiser 70 series........ Modern jeeps are unreliable trash........... Good luck getting a clean rubi or TJ unlimited.....
