Ok so i installed an RK 3.5" X-factor lift last weekend. everything went pretty good and it turned out awesome. So i was driving around and wanted to see how it felt flexing it out so while we were looking for asparagas i just drove up and down some ditches. coming out of the last bend I heard some grinding and when i stopped and looked the rear springs came out from their cupped seat and were rubbing on the track bar.. Is this normal or do i need to install something to keep this from happening. Its not a hard fix, just annoying. The kit came with spacers to put on the axle so thats good. coils angle a little toward the front of the vehicle. Ive also got bilstein 5100 shocks.
Any idears?

 

You can install upper or lower spring retainers to keep your springs seated. Are you running any bump stops with that lift?

 

Yes. front and rear Teraflex bump stops. but the rears im sure you know sit outisde the coil springs unlike the fronts that are in the middle of the coil springs. Shouldnt those retainers be included in a suspension kit?

 

I was looking at the site and it looks like that particular kit doesn't come with one. It does come with those rear coil spring wedges that is suppose to prevent it from bowing...you would have to purchase one....BTW how does the Rear track bar bracket install? Is it just bolted on or does it require any welding...Thanks...

 

No welding at all. You drill two holes and mount the bracket with two new bolts and reuse a factory hole. There are some pics of that. They arent great if you find my before and after pics. you can go into my photobucket and see it.

 

Thanks, is this the pic you are referring to? That bracket looks beefy, didn't see that bracket on RKs website/kit...



BTW nice Jeep love the color...

 

Here's the pic from the website. The picture of the bracket doesn't look like what you have installed. But if that's the bracket you have from the kit and it doesn't require any welding then this may be the kit I end up getting as well. Thanks..

 

your springs are likely bowing and hitting the trackbar, particularly on the passenger side.

There are three easy solutions: RK spring wedges corrected mine for now. Relocate or replace your factory spring perches. Install aftermarket adjustable spring perches. The third will allow you to change the angle if you replace your drive shaft and adjust your pinion angle, but your track bar relocation bracket will create some problems. Relocating the factory mounts or replacing them with aftermarket perches is probably the best solution. The spring wedges are the cheapest solution.
I have the wedges. I will relocate the factory mounts when I install an aftermarket rear drive shaft and have the pinion angle set where it needs to be for that shaft.

To keep your springs in I have seen where some people use hose clamps. You can loop a stainless hose clamp through the factory spring perch.

 

Yes that is the relocation bracket in the RK kit you posted. Thats what it looks like from the side view. It is beefy. Actually there isnt one part about the RK kit that isnt beefy.

Also the wedges you are talking about to correct the coil bending come with the RK kit as well. They are also installed and its not just the passenger side. Both sides come out. As soon as you flex at all they are going to come out. I dont see how they wouldnt. If they are only held in by the weight of the vehicle and you flex it out and its not touching anything, whats going to keep it from falling out unless its secured to something. Even with the wedges the springs tendency is to spring out towards the rear bumper. So you would have to have some sort of spring retainer on the bottom to keep it from falling off the axle and then at the top have something like the front bump stops to align the coil spring back up into its seat.

 

So when i eventually get new driveshafts that will correct my pinion angle, which will also help my spring situation? Which i mean will roll my axle back up towards the front of the vehicle enabling the spring from wanting to pull out towards the rear when flexed. If im getting this right....
