    I installed a 4inch RC lift about 3 months ago. All springs. However, today while changing my gear oil. I noticed that the 10* wedges in the back where missing.(the little thinks onthe bottom of the springs, about 5-6 inchs long.) The right side was gone completely and the left was craked through! What an i to do about with. There is about a 1/2 inch gap between the spring and the axle. I'm not sure how they broke or what to do about it?

    I would give RC a call and see what they will do about it since you just installed it 3 months ago. That is what I would do if it was me. That is just a small thing and it shouldn't be a hassle to get another set from them.

    same thing happened to a friend, RC 6"lift

    I had an extra shim so I gave it to him.

    If its the shim that's bolted to the spring pack, you gotta take the spring apart. If you're doin that I recommend you put back a zero rate or something better than but broke to begin with.

    I would advise a zero rate or the steel shims, if the shims from RC broke before the will probably break again.

    It's really easy to replace them. Unbolt the spring from the axle. Lower the axle out of the way a few inches. Then I just put a C clamp on either side of the axle pin to hold it together. Unscrew the axle pin, replace and take off the clamps.

    I don't care for aluminum shims. I've had nothing but bad luck out of them. My preference is for steel. Take a close look at the perches on your axle. Are they perfectly flat? You can weld steel plate to the tops of the perches if they aren't perfect. If they are really bad, replace them. Also, if your Ubolts aren't tight enough, that can kill the shims. I would use steel shims and retorque the ubolts after a few hundred miles and again after a few thousand.

    To swap shims, put C clamps on the spring pack before you loosen the Ubolts. Then take the U bolts loose, then lower the axle away from the spring, then take the center pin loose, install the new wedge, and put it back together. You will want to have a spare center pin before starting this process because they can be hard to reuse. Also, do it one side at a time for ease of installation.

    Glad to see they hooked you up with another set. If I have something go worng with a product I just contact them and tell them what happened and usually they ship off a new one for me. Had a problem with one of the Explorer Pro Comp Stainless Steel Braided lines and instead of one, they just sent me a whole new set of brake lines. :grin: Use a C clamp to keep the springs together and unbolt and replace.
