I'd like to say that I installed this lift in my garage in just 4-5 hours with simple hand tools. I bought a bench spring compressor and it was super simple swapping out the 5100s. for the factory shocks. I put them on the tallest setting so the spring had to be compressed more than with the factory shock but it was still super easy. Thanks Greg for all the advice. He will take his time and he answered all my questions. Even the dumb ones!!
