My rancho 9000's came with boots, but they weren't on the shocks. I got the 2 boots for the fronts on no problem, but the rears wouldn't go on over the already installed pins, so I left them off. Been about 2 years now and no problems either way. I also ran some Pro Comp 3000's for about 2 years with all the boots on, never had a problem. Lived in Utah at the time. If you like them, put them on, if not, leave them off. You'll probably upgrade, trash them in an accident, have to buy a different-length shock, or sell the vehicle before the seal fails either way.
