PROP 65 WARNING:

The Currie 70 high-pinion crate axle for the 2007 and newer Jeep JK Wrangler, is a complete bolt-in axle assembly with all required brackets and mounts in place. The vehicles factory driveshaft will require modification or replacement to accommodate the larger 70 series housing and 1350 series u-join

 

Built to the legendary Currie Standard with exclusive features including:

  Currie 70 high-pinion nodular iron center section is competition proven and the strongest casting we offer, with heavy main caps, ARP® main bolts and thicker walls and webbing in critical areas
     
Load Bolt   Ring gear load bolt (top left) eliminates gear deflection, to dramatically increase torque handling capacity. The load bolt typically sits .002 inch from the ring gear and only touches when extremely high torque loads are applied
     
RockJock 70 Gear   Currie's competition-grade gears (left) are cut from super-tough 9310 alloy, and then custom heat-treated to a precise hardness, creating gears that can stand up to both the high shock loads of extreme off-road use and the wear of high mileage street use. Standard Dana® 60 gear (right)
     
RockJock 70 35-spline pinion   Massive custom 35-spline pinion shaft (right), provides increased strength and reliability over the standard 29-spline unit (left)
     
  Currie 70 high-pinion radius bottom center section delivers unmatched ground clearance, and improved obstacle slide-over by presenting a smooth curve rather than the sharp edge found on other housings
     
  Replaceable AR400 hardened steel skid plate resists deformation and gouging to slide over obstacles far better than iron housings or mild steel plates
     
  Large diameter outer pinion bearing (right) is designed for the demands of reverse rotation/high pinion housings. Stock low pinion bearing (left)
     
  High volume flow-thru recirculating oil system keeps pinion bearings bathed in cool oil, reducing operating temperatures and eliminating oil starvation issues
     
  Large 3.5-inch diameter .375 wall axle tubes (left) are three times stronger than the stock JK Dana® 44 (right) without being overweight or sacrificing ground clearance
     
  Massive forged 1-ton inner knuckles (right) are designed to stand up to the severe punishment of larger tires without flinching
     
  Upper control arm mounts feature rebuildable Johnny Joints® for maximum suspension articulation with unsurpassed durability
     
  RockJock nodular iron front cover protects expensive internals, adds structural support to the housing's face flange and locates the driver’s side upper control arm mount
     
  Big 13-inch diameter vented rotors (over 1-inch larger than stock) provide the increased brake torque required for stopping large tires
     
  Large dual-piston calipers complete the RockJock 70's big brake package and provide the extra byte required to stop large tires
     
  Lower control arm mounts are one-piece construction with integrated skid plates to help fend off bracket seeking rocks
     
Powder Coat   Black satin powder coat finish adds long-lasting protection against rust and corrosion to keep your RockJock 70 looking its best

Notes

ABS Sensors - Does not include ABS sensors, the factory sensors from the stock axle must be retained and installed on the RockJock housing

Computer Programming: 2012 and newer vehicles require a computer programmer, such as the AEV ProCal Module to reset the gear ratio and tire height in the vehicle's computer for proper function of the vehicles stability control and transmission shift points

Brake Upgrade: The big brake kit included with the RockJock 70 uses 13-inch rotors with dual-piston calipers to provide the stopping power required for 37-inch and larger tires

Wheel and Tire Size: Requires 17-inch or larger wheels for proper brake caliper clearance. Maximum recommended tire size is 40-inches

Overall Width: Axle width is 70-inches (+4.6 inches over stock) between wheel mounting surfaces. Additional width improves turning angle with 37-inch and larger tires

Steering Stabilizer: Ram assist brackets are not compatible with and exclude the use of conventional steering stabilizers
