Trail-Gear 140275-1-KIT Rock Assault Front Axle Housing Features:

Knuckleballs are made of 1035 steel
Axle tubes are displaced above the midline of the housing, so the inner axles ride at the bottom of the axle tubes rather than in the middle
3/8 in. increase in ground clearance under the axle tubes
5/16 in. thick, high strength DOM axle tubes engage (5/8 in.) deeper into the center section, with a 360-degree gusset welded around the tubes on the inside of the housing
Heavy-duty, press-formed (1/4 in.) plate steel center section shell is uniquely constructed to provide an additional (3/4 in.) space beneath the differential
Differential mounting surface is constructed of (1/2 in.) plate steel

Notes:

To achieve maximum ground clearance, the bottom of the differential housing flange must be ground flush with the axle housing
Unpainted

Built for Tough Terrain
