When climbing rocks or blazing back woods trails, the differential is going to be exposed to potential damage. The Zone Offroad differential guard is constructed using a 7/8" solid steel ring supported by a 5/8" solid steel rod. This is all attached to a 1/4" steel plate. This rock solid design fits as tightly as possible to the differential for better ground clearance and to maximize the approach angle. To eliminate getting hung up on a bolt head, Zone uses button head fasteners powder coated to match the differential guard.
