The RockJock 60 high pinion crate axle is a complete rear axle assembly, reusing only the stock JK rotors, calipers and ABS wheel sensors 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 on the market (and that's including the integrated skid plate), guess the other guys can't read 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 Large diameter pinion bearings to handle the increased load of reverse geometry gears High volume flow-thru recirculating oil system keeps pinion bearings bathed in cool oil, reducing operating temperatures and eliminating oil starvation issues Large 3-inch diameter .375 thick axle tubes deliver superior strength without sacrificing ground clearance or being overweight RockJock Performance 40-spline 4340 chrome moly semi-floating axles, the largest and strongest standard axle in the industry Massive Set80 axle bearings allow for larger axle diameter through the bearing for increased strength
