RockJock 60 housing, 5x5.5 1/2" studs, 68.750" WMS, Detroit Locker - 5.38 ratio, Front

The RockJock 60 crate axle is a complete front axle assembly, reusing only the stock JK calipers from the vehicle. Built to the legendary RockJock Standard with exclusive features including: Rockjock high-pinion radius bottom center section greatly improves obstacle slide-over by presenting a smooth curve rather than the sharp edge found on other 60 housings Highest measured ground clearance of any 60 class axle on the market (including the integrated skid plate), guess the other guys have trouble reading a tape measure Integrated AR400 hardened steel skid plate resists deformation and gouging to slide over obstacles far better than iron housings or mild steel plates High volume flow-thru recirculating oil system keeps pinion bearings bathed in cool oil, reducing operating temperatures and eliminate oil starvation issues Upper control arm mounts feature rebuildable Johnny Joints for improved suspension articulation RockJock Performance full 35-spline (1.5 inch) 4340 chromoly inner and outer axles shafts for superior end-to-end strength (offered as an additional cost option from the competition) High quality and heavy duty components and brackets used throughout.
