I'm sorry but maybe I should have given a little more insight to my situation also. Thanks for the help this far.
I am running 35x12.50r17 kumo road venture MTs now and I do have a slip yoke eliminator and just bought a 1 1/4 body lift. I'm not trying to go huge and it rides surprisingly well...
I have a 3.5 rancho rock crawler lift with 1 1/4 teraflex coil boosters. JKS sway disconnectors, drop pitman and adjustable trackbar. My question is this I should only need springs and adjustable Upper and lower arms to increase to a 4-6" lift correct?
I used the stuff that the auto parts stores have it is rattle can bedliner. Armor something in the name. $13 a can and it is a rubber like texture coming on and it has held up great. I've done the tub and fenders and sliders. Oh yeah AND my bumpers I built.
