The RockJock 44 JK front crate axle delivers superior strength in a light-weight package that’s designed for heavy off-road use. Built to the legendary Currie Standard with reinforced center section, large diameter tubes and forged knuckles the RockJock 44 eliminates the common failure points of the stock JK front axle.

The RockJock 44 front crate axle is a direct bolt-in solution that reduces the overall cost by enabling you to retain the complete stock outer knuckle assemblies (brakes, hubs etc.) and stock wheel bolt pattern.
