I figured id post up here as well. I have a 3.5" fabtech spindle lift with 1" rear blocks from my 2011 silverado thaI just sold. It will only fit 2wd's. I ran the lift for about 5k miles, and I took it off before I sold my truck. I ran 35's on just the spindles and a 1" leveling kit. I paid right at 800 for it and I'm asking 500 obo. Its a good price considering its not a part that can wear out. It is complete with fabtech tre's and I still have the instructions. Pm me if interested and I'll send pics of the kit, plus pics of it on the truck. It doesn't change the steering geometry or ride.
