For Anyone wanting to run RCX 3.5

So this thread is probably moot as I do not own my 2011 Silverado anymore but I feel I could give a little insight of the issues I had with my RCX 3.5" lift, I purchased the kit with the UCA for Christmas and did the install myself (very proficient with suspension installs as a DIY person). After the install I took the truck to 4WP to have an alignment where they told me that it would not be perfect as the angles were no where that they should be (meaning the TRE and LCA and BJ) the UCA BJ was at a decent angle (as it is supposed to be with the kit) and after the alignment they had it as good as they could get it (I have the paperwork somewhere I think). But I just want to enlighten some of you newer guys who want to put this kit or others like it on your truck to some issues I had. 4WP told me that the tallest leveling kit I should run "shall not be over 2.25" or it will begin to severely wear the suspension components", me being young I didn't care. I put approximately 30,000 miles on this kit before I had issues, some mild and a few times with hard offroading (2-4 times I cant remember). The ball joints popped out of the UCAs and the LCA BJ were shot, as well as the TRE. I ended up replacing the whole kit with the Procomp prorunner shocks that gave the 2" level and had zero issues (ride quality was shit for me as I had 33" mud graps on it and Chinese mud grips )

I've had friends go with this setup on 35" graps and have 0 issues, but those were street driven.

I don't want to turn anyone away if they have heard better or feel it would be okay for their setup. I just want to enlighten my issues with RCX 3.5" lift w/ UCA. Installation has you drop the diff which is a plus and you have to cut the crossmember for the rear of the LCA bracket, but overall wasn't horrible.

If you have question I can answer to best of my ability, my 2011 Silverado 1500 Z71 4x4 was running a procomp prorunner 2" shock level with 33" mud grapplers and had the wheel well liners ziptied back and I am pretty sure NORCAL mod done to fit them.
