Crate Axle RockJock 60VXR Rear JK 60VXR Housing, 5x5.5, 1/2 Inch Studs 70 Inch WMS 4.88 Ratio

Product Description: 

The RockJock 60VXR high pinion rear crate axle is simply the strongest 60 series axle that we offer, designed for extreme off-road use with up to 40-inch tires and V8 conversion horsepower.

The RockJock 60VXR is built to the legendary Currie Standard and loaded with exclusive features including: a stronger reinforced stage-2 radius bottom center section ring gear load bolt, large 3.5-inch axle tubes, full-floating axles and bigger brakes plus much more. If you seek out the most challenging routes and toughest obstacles to conquer then the RockJock 60VXR is the crate axle of choice.

The RockJock 60VXR is a complete rear axle assembly, reusing only the stock JK ABS sensors from the vehicle.
Built to the legendary Currie Standard with features including:

  • Locker: ARB Locker
  • RockJock Stage-2 high-pinion nodular iron center section is simply the strongest 60 series casting that Currie 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 1/2 inchinch diameter, .375 wall axle tubes maximize strength and resist trail damage without sacrificing ground clearance or being overweight
  • Full floating design isolates the Currie 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


  • Center Section RockJock Stage-2 high-pinion nodular iron radius bottom center section with thicker walls and webbing
  • Bearing Caps Stronger, increased cross section bearing caps with ARP fasteners
  • Pinion Bearing Large diameter front pinion bearing matched to rear bearing
  • Pinion Oiling High volume flow-thru recirculating oil system
  • Gear Set Standard Dana 60, compatible with super 60 reverse cut gears
  • Ring Gear Load Bolt Eliminates ring gear deflection under heavy load (3/4 inch-16 right hand thread with Jam nut)
  • Pinion Yoke 1350 u-joint
  • Skid Plate AR400 hardened steel skid plate
  • Differential Cover Currie nodular-iron cover with gasketed fill plug with dipstick, Red
  • Axle Tubes 3.5 inch diameter. .375 wall DOM tubing
  • Axles Currie Performance full floating 35-spline (1.5 inch diameter) 4340 heat treated chromoly
  • Floater Spindle Currie Performance 2.5 inch 4140 Chromoly spindle, supports 35 or 40-spline axles
  • Floater Hub Currie Performance hubs with 35-spline drive flanges, JK tone rings installed for ABS and ESP retention
  • Brake Rotor 13 inch vented rotors with zinc plated caliper brackets
  • Brake Calipers New factory JK rear Calipers
  • Suspension Brackets Heavy gauge 3/16 inch steel mounting brackets with multiple mounting locations that enable the suspension geometry to be tuned
  • Geometry Optimized for 4 inch lift kits with 5 degrees of pinion angle to reduce driveshaft
  • Width 70 inch wide (between wheel mounting surfaces), enables increased turning angle with 40 inch tires
  • Wheel Bolt Pattern 5 on 5 1/2 with 1/2 inch wheel studs
