RockJock 60VXR housing, 5x5.5 1/2" studs, 70" WMS, ARB Locker - 4.88 ratio, Rear

Built to the legendary RockJock Standard with features including: RockJock Stage-2 high-pinion nodular iron center section is simply the strongest 60 series casting that RockJock offers, with 9lbs more reinforcement in critical areas over the already strong Stage-1 center section 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 have trouble reading a tape measure Load bolt eliminates ring gear deflection, dramatically increasing the ring gear's torque capacity Large front pinion bearing to handle the increased load of high pinion geometry Strong 3 1/2inch diameter, .375 wall axle tubes maximize strength and resist trail damage without sacrificing ground clearance or being overweight Full floating design isolates the RockJock Performance 35-spline 4340 chrome moly axles from the stresses of vehicle weight and side loads to provide superior strength 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 eliminating oil starvation issues"
