The Motobilt lower coil over mounts for the side of the axle are built to take some serious abuse. These mounts have a set of built in spacers that will work with 2 inch coilovers. The brackets come as a pair and will need to be welded together for install. They are designed to fit 3-3.5 inch axle tubes. They are laser cut from 1/4 inch thick steel plate that is CNC formed in house at Motobilt HQ for a precise fit.
