I know 37 will not fit on hers, I had to trim about 3/4" off the chin spoiler cause they rubbed when in a sharpe lock turn. This is the Donahue 3.5" lift. She wants to go higher now cause shes not as big as some of the trucks in town now..LOL So im looking for the stuff to take her up, I already have the new 20" XD KMC Monsters for it, no just looking for a nice slightly used 8" lift..
