Just used this method to cut the springs on my Dodge Dakota. Got a perfect 1" drop, one and done, no repeat cuts to get it where I wanted or worrying about cutting too much. They don't make 1" lowering springs for this application so this worked perfectly for me. Thank you!!
I’m planing on doing this on a 1957 buick that I built on a 1985 Cadillac frame. I understand 1 is 2 because the way the front suspension works but what about the back? Does 1” make 2 at the wheel?
This video is the meca of coil springs I’ve been looking for a way to lift my old van, and nothing and then I found this nice piece of film, wowww thank you Jesus and thank you guys
As another commenter pointed out, the 1:2 ratio depends on the length of the control arms. The springs sit further in than the tire, so dropping the spring height by 1" means that the tip of the control arm is moved by 2" because of its length. I just cut my springs and it was pretty close to 1:2. Thanks for the vid.
This formula doesn't really work except for the first cut on a new spring. Each time you cut coils off, the spring gets weaker and the spring rate decreases. So while 1 coil may = 2" of drop the first go around, subsequent cuts will net even more drop because the spring will compress more since there's less coils to absorb the weight. Also, the ratio is entirely dependent on spring rate. Half a coil on a 500 PPI spring might = 2" of drop, but half a coil on a 1000 PPI spring isn't.
@@jjjones518 The spring rate would increase, how much it increases will depend on the spring, could be very little or it could be a quite a bit. An increased spring rate is generally required when you lower a car anyway, so this isn't necessarily bad; however, you may need to change your shocks to something with more dampening or the car might ride bouncier and prematurely wear out the shocks. The shocks might have to be changed anyway to stop the springs falling out since they're shorter.
I appreciate what you explained on this full detailed video Sir. Thanks for teaching us with the knowledge you have on trimming springs for GM vehicles. I have a 2005 Chevy Tahoe on huge 28" wheels with low pro tires. I bought a 5" full lowering kit that Came with extenders coils shocks and sway bar studs. I thought i was going to have the job finished and have my Tahoe lowered how i wanted too, but i still see some gap between the tires and the fenders. My goal is to tuck in just a lil into the rear fenders. So im guessing like a inch or inch and a half. Maybe inch and a quarter i dont know the exact measure but im going to talk to my installer and have him finish the job. Im sure he knows what he's doing. I wanted to do a research myself before I take it back to him so i know somewhat of what he'll be doing. He installed my lowering kit about four months ago so im good to go i know that after you install a kit you have to drive it around for a bit then have all the bolts & nuts tight up again with the proper torque it requires. Anyway Sir, thanks once again for this and have a blessed day. 👍
Used this formula for a 1997 v6 silverado single cab. I ls swapped it and wanted it lower 15 .25 tall spring trimmed it to 14.25 and it gave me a 2 in lower. Compensate for the chevy lean the driver side is just a bit taller
Like the technique or no i just completed it on a 65 impala dropping my front end 3 inches side to side measurements came out exactly the same thank you for the video.
Great video! I never knew this. Thanks! I just put some Moog coil springs in the front on my third gen Camaro. They are just over 2 inches taller side by side out of the car compared to the stock ones. I may have to do this. In the car they are about 3" too tall. So frustrating when you spend all that time installing and the company can't make the proper fit.
Great process thank you! Can a C-10 1963 rear could be trimmed? I ask because c-10 rear has smaller diameter sections on each end than the middle is. So I’ll measure as you taught us to see if the coil will be small enough to install. Thanks
Thankful for your sharing here buddy.. that's some critical info. If you doing a proper chop job -(can ya say that?) Feel like I been given gold 'Im telling ya' 😅 & Looks like you work alil to much or to hard maybe- so cheers for your time. Appreciate it! .. 🎉 ..sharp guys ✌️
It's a lot of work but I still like the quarter coil cut put it back together drive it see where it sits if you want it a little lower take it out take another quarter and so on. You can always take more away you can't add it back.
Should one cut the top or bottom of the spring? My S10 springs are the same on top and bottom, but the lower control arm has a step for the end of the coil.
This is a good quick explanation of how ride height is affected but doesn't address how this will increase spring stiffness. If your suspension is already uncomfortably stiff then cutting your springs will only make that ride quality worse. The major manufacturers have many engineers to figure out a good compromise, it's when you go for a custom build that this can get tricky.
Will be doing this on the front of a 64 Corvair van in the near future. Rear springs are sold for this purpose and drops rear almost 3 inches, which also changes the rear camber. (the whole idea) Those are a smaller wire diameter, which softens the ride a bit. (better because the back is now empty) The question is about issues with suspension travel. Obviously there is less room downward, but this will increase the upward travel and using stock shocks won't limit that. Do I need to change anything else?
Very informative video, to the point. My old Crown Vic isn’t a muscle car but being body on frame, the front suspension really ressembles to the old Chevelle’s and likes from that era. Would this 2:1 ratio formula work? Also would this procedure make the suspension stiffer or softer, thanks for your input ;)
Great Video! I had a question, My 2010 Mercedes CLS 219 had both its rear coil springs replaced recently as they were fractured. Following replacement, the rear ride height seems to be a few centimetres more than it was previously. Is this normal? In time, will the rear ride height go back to how it was on the old springs that were replaced? Many thanks in advance.
Going to try this on my 2002 chevy blazer xtreme 😬 wish me luck guys And can you please do an episode all about sway bars and endlinks and what is a proper set up for different utilities
Thanks for your informative video. I have a 1953 Chevy pickup with Ford Mustang II suspension. So my truck is a GM/Ford application. Does the formula, 1 at the spring 2 at the body, work for this application? Thanks for your reply!
"We've done it for years. Works every time." What is the explanation for the 1:2 ratio, considering the fact that spring rates vary? Are we assuming that the spring is at half its height when it's under compression with the weigh of the car? Is that always the case?
Picture the lower control arm viewed from the front of the car. See where the control arm is attached to the frame. Then see where the end of the control arm is attached to the spindle. Then notice that on gm cars of this vintage, the coil spring is sitting roughly in the center of the control arm. With this info, you can conclude that for every 1 inch of movement of the spindle up or down, the corresponding movement at the spring is roughly 1/2 inch. Therefore it is a 1:2 ratio. As a contrast, picture the coil spring being mounted directly above the spindle. In this case, every inch of spindle travel would be equal to the springs movement. Therefore, 1:1 ratio.
Doug, thank you for all of your videos they are so incredibly helpful. I just replaced a really poor version of tubular lower control arms in my 64 Malibu SS. Unfortunately after I was done the car is now sitting 1-1/2” higher and this video of cutting coil springs was invaluable for me. A question on my stock sway bar, after reinstalling this I noticed the mounting stud for this at the control arm is leaning towards the rear on both sides at least 45deg. Is this okay or are they supposed to be perfectly vertical ?
We appreciate the feedback to our channel and will pass the word to our man Doug! This sounds like a great question for our Tech Experts, give them a call at 877-470-2975
I ran into that very problem today. What you have to do is measure the distance between the coils toward the middle. That distance is the distance to go by.
Great video. Question for you. I have a 72 Nova I need to drop in the front after installing Moog springs. I believe there is a "notch" or "pocket" on both the upper and lower control arm. After the cut, which notch or pocket do I use when reinstalling the spring (top or bottom arm)? Thanks for the help.
But what about cutting stock Oem springs cut down to 3" put new drop shocks in ok or the other way buy 3" drop coils An new drop shocks ? What's the difference? Like bottoming out An like how do they compare in stead of buying 150 coils if done the correct way as mentioned in the video. Also how bout mono leafing the rear cause I've see the drop leaf springs An they have 2 leafs ? But agian as far as bounce An spring wrapping around rear axle are the after martek drop coil springs and lowering leaf spring much stiffer metal much stronger solid not as easy to flex or are they basically similar to OEM just trimmed down?
So if it has the double coil type seat on both ends, it's cutting an option? I haven't cut the springs on my grand prix after new struts cause i just don't see how it'd work. I put new struts on and it gave it a 2 inch lift kit... thing looks ridiculous that was a year ago they haven't settled at all
Is there a reason why this wouldn't work on a Lexus with the same type of coil spring? I'm trying to envision a scenario that would make the math different, but I can't come up with one. Thanks! Great video!
it has to do with the length of control arm from the bushing to the ball joint and where the spring is if the spring is way close to the pivot point a small change in spring length would make a big change in ride height if the spring was located farther outboard it would make less change in ride height
Was that 1 at the spring, 2 at the body rule for the fronts? For the rear, and for a live axle, wouldn't it be 1 to 1? For other cars, can I work out my own ratio by measuring the length of the lower control arm and where the spring perch is? If in the middle, 2:1. If farther out, less than 2:1.
So where is the measurement cut? If it's 14.5 the top middle or bottom of the coil? Because if you cut 14.5 as soon as it hits that mark it's at the top but if you go a lil further the mark would be at the bottom or even middle
Like he said measure the coil say it say 14" cut a .5" off see were it sits its gona be annoying taking ur coils in an out for checking but better then cutting to much or if you have the money buy sum aftermarket ones but jus cut a .5" lil by lil see we're ur height is at
Finally found what ive beem wonding for 20 years lol thanks..i knew there was a way to add some math to it other than guessing at it lol now if i can find how to do my Harley Davidson front springs
So does this go for buying drop springs also? Say I want my front end lowered 2", would I buy a 1" drop coil? And is that recommended or is cutting it just as good & safe? Its a 62 belair with factory coils
john jones you may end up with clearance issues and possible bottoming out,severe bottoming causing damage to whole front end and steering components. Can be avoided by changing your driving habits permanently and drive very slow like old school lowriders. As this was the only way to compensate for the lowering drawbacks.
I would think that IF the top is ground flat, you can rotate coil so bottom tang is in the correct spot. You do bring up a good point in cases where the spring isn't ground flat on one end. Usually there is an isolator which can rotated at the top.
@@ryanmacewen511 yes but the top isolator on a strut at least, cannot be rotated from its correct position becuz its angled to hold the spring a certain way.it has to be aligned correctly with the strut to hold the spring properly... cutting the bottom coils though, should be ok as long as the top coils are flat or squared off...leave the top cap aligned on a strut, rotate the bottom cut spring in the strut to seat it in its locked position..
Where I'm lost is the bottom coil differs from those above, which are consistently 1" apart (approx.). The bottom coil starts to flatten out for a more conforming surface where it sits on the control arm. If you cut the coil it will have lost that conformity. Doesn't matter?
I've heard that you risk having the coil pop out at full suspension drop. But then again, tons of folks are cutting these squared-off springs and plopping them in their control arms without a peep. Have you found more out on this? I have the exact same question.
I did a LS swap in my 80 firebird and Have a weight reduction of at least 80 lbs (iron motor vs alloy). It looks like it's sitting at least 2-3" higher in the front. How will cutting the springs effect it considering the weight reduction? My guess logically would be a firmer ride! When I bounce the front end now it seems way springier than before.
cutting your spring wont chance the load it will take. your front end is sitting higher than before giving more travel is the reason its bouncier. cut half a coil put it back on & check the height.
I am sorry you are having a hard time finding what you need. Unfortunately we don’t see a high demand to do r&d for this particular application. We do wish you the best of luck for your awesome vision.
Do a 73 through 87 Chevy C10 front spring they are different than the one you are doing it is smaller at the top and has a compressed winde at the bottom

This method worked great on my c10, I had to cut different amount on both sides to get the ride height I wanted.
glad to hear it worked!

Hello
This springs are right for any car
no not all cars use the same springs
Was that 1 at the spring, 2 at the body rule for the fronts? For the rear, and for a live axle, wouldn't it be 1 to 1?
For other cars, can I work out my own ratio by measuring the length of the lower control arm and where the spring perch is? If in the middle, 2:1. If farther out, less than 2:1.
Interesting formula !
Trimming springs by Inch? Won't it destroy the stock suspension?
trimming the spring will modify the stock suspension of course
1 at the spring is 2 at the body. Simple + to the point.
So where is the measurement cut? If it's 14.5 the top middle or bottom of the coil? Because if you cut 14.5 as soon as it hits that mark it's at the top but if you go a lil further the mark would be at the bottom or even middle
Same formula for Belltech Spring? Or is that formula only for a GM spring
We only recommend this formula for GM!
does this work on newer cars or trucks? I have a 2008 Silverado would it work
Like he said measure the coil say it say 14" cut a .5" off see were it sits its gona be annoying taking ur coils in an out for checking but better then cutting to much or if you have the money buy sum aftermarket ones but jus cut a .5" lil by lil see we're ur height is at

Does this formula work for all spring rates?
like the video said we recommend this for GM only
Do i need to grind the cut flat ?
Should you got the top or the bottom
opposite end of where the coil is flat
Would this formula work on say one side of the car? If you happen to have the car leaning about one inch more to one side?

So does this go for buying drop springs also? Say I want my front end lowered 2", would I buy a 1" drop coil? And is that recommended or is cutting it just as good & safe? Its a 62 belair with factory coils

you may end up with clearance issues and possible bottoming out,severe bottoming causing damage to whole front end and steering components.
Can be avoided by changing your driving habits permanently and drive very slow like old school lowriders. As this was the only way to compensate for the lowering drawbacks.

Could u help me with the ratio of THE REAR spring please???
Thank u🙂

@@GlobalWestSuspension THANK YOU
no offence but shouldn't you cut only full winds so position of spring at mounting points stay the same?
I would think that IF the top is ground flat, you can rotate coil so bottom tang is in the correct spot. You do bring up a good point in cases where the spring isn't ground flat on one end. Usually there is an isolator which can rotated at the top.
@@ryanmacewen511 yes but the top isolator on a strut at least, cannot be rotated from its correct position becuz its angled to hold the spring a certain way.it has to be aligned correctly with the strut to hold the spring properly... cutting the bottom coils though, should be ok as long as the top coils are flat or squared off...leave the top cap aligned on a strut, rotate the bottom cut spring in the strut to seat it in its locked position..
Follow the formula it works!
How much i have to cut the springs
Well if i have to lower the car for 3 and 4 inches
great video. this makes lots of sence. good job. Im doing it this way for sure
Awesome, thank you!
Where I'm lost is the bottom coil differs from those above, which are consistently 1" apart (approx.). The bottom coil starts to flatten out for a more conforming surface where it sits on the control arm. If you cut the coil it will have lost that conformity. Doesn't matter?
I've heard that you risk having the coil pop out at full suspension drop. But then again, tons of folks are cutting these squared-off springs and plopping them in their control arms without a peep. Have you found more out on this? I have the exact same question.

What about the springs on a strut? If we're to measure and cut about half inch from spring. Does it stiffen the coil any?
visit a local shop for specific expert advice!
Would I be able to do this on a 97 Silverado????
Bearded Panda you ever find out?
It may vary!
Same process for springs that are already on car and you want to cut those?

great video i may do this to my 83 c10 if i do ill be sure to make a video and hope you guys see the results
Awesome to hear hope the video helped!
What is the most you could cut a spring?
until the wheel arches are scraping the sidewall of ur tire lol
Talk to a professional before you cut your spring!
I did a LS swap in my 80 firebird and Have a weight reduction of at least 80 lbs (iron motor vs alloy). It looks like it's sitting at least 2-3" higher in the front. How will cutting the springs effect it considering the weight reduction? My guess logically would be a firmer ride! When I bounce the front end now it seems way springier than before.
Ha I'm running a BBC and I'm 2" higher than normal 🤷🏻♂️.. maybe over the winter. I'm gonna cut that 1" off ..
cutting your spring wont chance the load it will take. your front end is sitting higher than before giving more travel is the reason its bouncier. cut half a coil put it back on & check the height.

Would be nice if there was springs to drop a 94 vandura 2 or 3 inches. Or maybe some dropped spindles that werent made for something else.
I am sorry you are having a hard time finding what you need. Unfortunately we don’t see a high demand to do r&d for this particular application. We do wish you the best of luck for your awesome vision.
Awesome video love it
Glad you enjoyed it
is this safe for a 2014 camaro?
Anything for Ford mustang's?
Haven't made a video on mustangs yet!
Where you measure the drop does it have to be inline with where the springs are?

Great video and the information worked perfect!
Great to hear!
Do a 73 through 87 Chevy C10 front spring they are different than the one you are doing it is smaller at the top and has a compressed winde at the bottom
All springs are different!
Thanks mate good vid.
Is that gm as in general motors and if so does this include saturn??
yes as in general motors
Hey mate.Ive cut 1.5 inch to get 3 as U say.Still sits high,will it sag over time?
Depends on the spring manufacture whether they prestressed the coil or not. If they did it probably will stay. If they did not it will sag.
