I had the 8" Fabtech on my last truck (02, 2500HD, 4x4) and it was ok. Wasnt real impressed with Fabtech as a company though. Not real helpful when I contacted them a few times with steering problems. I am looking at the CST 9-11" Lift for my new truck (06, 2500HD 4x4, Diesel). I had Adam at Wired for Sound quote it. I also talked to the Guys at TAG motor sports on the 8" Fabtech (8" is as big as they go). They said they dont sell the CST because they dont like the steering setup. Anyone else heard anything about this?
So far I think I am going with the 9-11" CST and maybe add the Fabtech steering kit. Anyone know if they will work together? I think the steering upgrade is a must since I went through 3 sets of Idler and Pitman arms on my last truck. The consensus here and from everyone I have talked to seems to be that CST is the best lift out there
