Bowed springs and correction pads?

[Fast-n-Furious]

So I have a set of front and rear Clayton coil springs sitting in the garage for a while, I'm planning to get them installed soon. I've noticed some slight bowing of my current XR front springs, more obvious on the driver side. The Clayton coils have higher spring rates, which I think will reduce the bowing a bit.

I'm also thinking about getting a set of front coil spring correction pads to replace the lower OEM isolators. There are a few options.

- MetalCloak Front Coil Correction Pads
- RUSTY'S JL/JT BOW CORRECTION LOWER COIL SPRING ISOLATORS
- Rancho RockGEAR RS62123 Coil Spring Insulator
- Rock Krawler JL/JT Front Spring Correction Pad 18-Pres Wrangler (they also have upper isolators)


Any thoughts on these coil correction pads? Which one would you prefer? It seems no one really replaces the rear coil isolators. Some folks also mentioned rotate the upper rubber isolators a bit, but I remember there's a hole in the metal housing that the rubber piece has to be aligned.

Park your Jeep on level garage floor, make sure tire pressure is the same and carefully check ride height at each wheel. Also measure to verify the front axle is centered side to side (this will create some spring bowing if off center) and if it's not centered, install an adjustable track bar (great idea in any case) and adjust to center.
Be careful on the aftermarket 'correction pads' as left and right are identical, some of the OEM pads are different height from left to right front. I found this out when changing suspension on my '20 JLR and wound up tossing the aftermarket pads and put the OEM back in-zero issues in nearly four years.

Thanks for pointing that out!

@Metalcloak what’s your insight on the correction pads? Do you think I should get a set of front ones when I swap the coil springs? And why you guys don’t make a set for the rear?

Our correction pads should help out. It is pretty common to see the bow you have with aftermarket coils including the mopar lift coils. The stock coils we normally don't see bowing with.

The rear we haven't seen a need for since they don't have that issue. Bowing in the rear is normally from the pinion being adjusted too high. Really common with the stock shafts that need to have more angle to ensure proper lubrication.

Thanks for the reply! My front coils are still the stock XR, I’m surprised they are bowed.

Do you suggest to replace the upper isolators as well when I swap the springs? I don’t see you guys make the matching pads for upper.

Unless you have a ton of miles on them, I wouldn’t worry about the upper isolators. Just make sure they aren’t pinched or cut and reuse them.

Thank you Sir! Mine only has 15k miles.

As others have said if yours are.good you can reuse them. Our springs require a different upper isolator that we include with the spring.

James @Clayton Off Road I’d like to get your opinion on which correction pads would work the best with the 392 performance coils. Essentially the front ones are the 2.5” springs, so really not 392 specific. I don’t see any comparisons among the few options I listed, figured you may know more.

Just food for thought:
Below are pictures of lower front spring isolation pads, first picture are Mopar/OEM type isolation pads from my original Mopar lift and the second are aftermarket (all aftermarket ones are the same design) 'correction' pads...When I installed the aftermarket 'correction' pads my JLR was not level side to side, pulled them out and reinstalled the Mopar ones that came in my first Mopar suspension kit and back to level!


Note: OEM pads are specific Left and Right and can be different heights side to side based on model and equipment. They are also mirror image, in the picture they are 'clocked' to show the height difference but the locating pin on the left one is on the right (you can see this) and the locating pin on the right is on the left, (Cannot really see the pin but this is why the right one is not sitting level on the bench)

All aftermarket isolation or as they call them 'correction' pads are identical, no height difference and no independent left and right.

Thanks a lot for posting the images. I took a closer look of the front driver side today, had to crawl under behind the wheel to get a better look. There are INDEED different, just like what you described.

@AllMoparParts.com do you know the part numbers of front coil spring lower isolators for my 2022 392 XR?

 

[Fast-n-Furious]

@Metalcloak do you have any insights why the factory lower isolators are not designed with the same thickness left and right while the MC correction pads have the same height?

@AllMoparParts.com do you know the part numbers of front coil spring lower isolators for my 2022 392 XR?

Sure L/R are the same 68342245AC

Please let me know if you have any other questions.
Thanks,
