The Mojave sits level because of the Springs being 1" taller than all other Gladiators.. so a 1" spacer should do the trick. IMO I would be looking for a 1 or 1.5" spacer. Lift if you are planning on going to 35s or 37s on your Willy.. BTW what is your planned off road activities?What size lift kit or what do I need to raise the front end up on my gladiator willys.
