As you may know once you lift your Jeep the rear coil is "bowed" rather than perfectly straight up and down. They sell a 10 degree plate that corrects this. Is it worth the hassle or not? Will the plates improve the ride or function of the spring?

They are only $20 a set but a little bit of a pain to install so I want to make sure it is worth the effort.

Also, which are better steel or Poly? I'm thinking Poly may reduce noise and vibration.

Facts or opinions, please.

 

I have the synergy ones. They do their job. And honestly they are not that hard to install. Can be done in about 20 min total. Lift the rear of jeep using the pumpkin. Put jack stands below the rear doors on the frame rails as far back as you safely can and the just lower the axle till the springs loosen enough to get the wedges in. Jack it back up and take stands out and lower it back to ground. Can't comment on the ride quality part. I don't think it makes a difference really.

 

Might have to take wheels off. Add 10 min. Lol.

 

Cut the factory ones off rotate them until they are back on top of the axle and weld them back on. Pretty easy to do it the right way and it is free if you have a welder.

 

I have the RK wedges. Before installing (which took about 20 minutes, as previously stated) the spring on the passenger side was contacting the JKS trackbar. Now it doesn't. 2.5" TF lift, but with OME HD rear springs when running with MBRP rack on the hardtop.

 

I ordered the Rock Krawler polyeurathane and I will go to Harbor Freight and get two sets of the strut spring compressors and try to compress the springs with the weight of the jeep on the springs then using a 6x6 I will jack up the rear from the receiver and slide them in. The spring compressors are $14.99 / set.

 

If you don't have jack stands then I would just invest in that and follow the steps I mentioned already. Will spend half the time and do half the work

 

I agree. I have spring compressors and they weren't very helpful.

 

This is what I used on my RK wedge install. Couldn't be easier.

 

I had to put new perches on mine. Artec was the best, theirs have a feature to correct then perch forward 1" if you've moved your axle back (like an RK lift does). Excellent quality.
