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

The RockJock 60VXR high pinion front 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 and big brakes with upgraded master cylinder and booster 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.
Built to the legendary Currie Standard with exclusive features including:

• RockJock stage-2 high-pinion nodular iron center section is simply the strongest 60 series casting we offer, with 9 lbs. more reinforcement in critical areas over the already strong Stage-1 center section
• Locker: Detroit Locker
• Radius bottom center section greatly improves obstacle slide-over by presenting a smooth curve rather than the sharp edge found on other 60 housings
• Integrated AR400 hardened steel skid plate resists deformation and gouging to slide over obstacles far better than iron housings or mild steel plates
• Ring gear load bolt eliminates deflection, to dramatically increase the torque handling capacity
• 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
• Currie Performance 35-spline 4340 chrome moly inner and outer axles for superior end to end strength
• High volume flow-thru recirculating oil system keeps pinion bearings bathed in cool oil, reducing operating temperatures and extending bearing life
• RockJock nodular iron differential cover with integrated upper control arm mount features rebuildable Johnny Joints for superior articulation and service life
• Currie Currectlync 1 5/8 inch diameter heat treated chromoly tie rod for unsurpassed strength and reliability
• Big 13.250 rotors and dual piston 1/2 ton RAM truck calipers with volume match master cylinder and booster for optimum brake feel and performance

Note
Brake Upgrade: The big brake kit included with the VXR60 uses 13.25-inch rotors with dual-piston calipers to provide the stopping performance required for 37-inch and larger tires. In order for the larger calipers to function properly the stock booster and master cylinder must be upgraded to larger units, which is why we've included an upgraded MOPAR factory master cylinder and booster with the RockJock 60VXR.
Wheel Size: 17-inch or larger wheels are required for proper clearance of the brake calipers
