When you want to have an offroad truck than can handle offroad tasks you need to stop listening to the mall crawler shops and go with people that do offroad for a living and know a thing or two about the parts they make. Thuren, Carli,SynergyMFG etc. It's a tough spot to be when the only thing you get in your eyes when you ask is 5100 here or there. Otherwise everybody else is doing chitty spacers cause they only care for height with deep dish 22's. No offense of course if this is what you're looking at. Most issues with spacers in the live axel world is improper shock length, incorrectly set bumpstops, incorrect shock valving. Ask anybody here for shock specs or coil specs and see what you get... Lol they know couple of brands and model numbers and that's about it...
