it will ride stiff. the pro comps are short aal and are thicker on the stock leafs. however, i like them. it solved my sagging issue on my 4runner. i just had to crank my t-bars a little to leave the 4runner out.

as for the body lift, you need atleast a floor jack and common hand tools (sockets, wrenches, a philips, etc). air tools are nice since it helps to break the body bolts loose. it's an all day event especially since this will be your first one. take your time.

and btw, good luck.
