Very easy installation. I'm not a pro and I managed to mount a 2" Rough Terrain Lifter in the front and 2" Off-Road Freedom Coils in the back on a jack in my garage in just under 4 hours by myself. There were instructions but I didn't really look at them. Before installing, just watch a few videos and get started. Would buy again and again. There were a lot cheaper 2" front spacers out there but I wanted to buy a name I knew and it was worth it. I had to cut the top rack studs about 1/4 inch. It wasn't difficult, I just used my saw with a metal blade.
