Thanks you guys, at first I was going to hire a shop but I think I can get it done myself. I am definitely going to rent a spring compressor to assemble the fronts but I should have been more specific.

I wanted to know about the parts like top hats, washers, nuts, bushings etc. that are usually removed from the stock setup. I want to build the shock/spring setup before I remove the original setup from the truck so I can easily swap them in. My 4R is a lease so I wanted to be able to easily swap it back to stock if I don't wind up buying it at the end of the term and then sell the lift fully assembled.

I was hoping someone who has completed the installation could let me know exactly what parts are moved over from the stock setup so I can price out the parts to see if it is worth it.
