Well I finally got my 6 inch RCD lift on my new LLY, and let me tell you I was really impressed with the kit. It truely is a very well made lift. Ive lifted the last 3 GM trucks Ive owned useing the Trailmaster, Rancho and now RCD, and by far this kit is superior. It took me and a buddy about 15 hours with a hoist. I was really impressed how well everthing came apart, ie the ball joints, torsion bars, tie rods,half shafts, it was just like watching TRUCKS on tv, we had the front end completely torn apart in about two hours. Lifting a truck that had just a little over a thousand miles on it is alot different than doing one thats a couple years old. The instructions were poorly written and we had to just figure alot of it out as we progressed. But anyway I post some pics in the next day or two. As it turned I can barely fit it in my garage, the Onstar antenna actually bends back going in. Now thats a tight fit.
