I have this on my truck , it will lift the rear 2 inches and the front 3 I got mine for $185 shipped you will probably want to get new longer shocks, I did
looks really good with 33"s had to do some minor trimming of the plastic on the GMC not sure about the chevy. this is with 18x9 rims that move the tires out a little. maybe no trimming with stock rims. it says the kit will clear 35" with some trimming but I don't think so
