The RockJock® 44 front crate axle is a direct bolt-in solution that reduces the overall cost by enabling you to retain the complete stock JK outer knuckle assemblies (brakes, hubs, etc.) and stock wheel bolt pattern.

 

Built to the legendary Currie Standard with features including:

  RockJock 44 high-pinion nodular iron center section features 14 lbs of reinforcement over a stock 44 with thicker walls and webbing to deliver superior strength and rigidity
     
  Large 3-inch diameter .375 wall axle tubes (left) are more than twice as strong as the stock JKs Dana® 30 tubes (right) without being overweight
     
  RockJock heavy duty forged inner knuckles (right) are massively stronger than the stock knuckles (left) and are designed for severe off-road use with up to 37” tall tires
     
  Currie Performance 4340 chromoly axles with larger Rubicon 1350 u-joints provide superior end-to-end strength over OEM carbon steel axles. Black oxide coating helps protect form surface corrosion for improved durability
     
Synergy HD Ball Joints   Synergy Manufacturing® heavy duty ball joints provide improved reliability and long service life with big tires and heavy off-road use
     
  Upper control arm mounts feature rebuildable Johnny Joints® for improved suspension articulation with unsurpassed durability
     
  Lower control arm mounts are one-piece construction with integrated skid plates to help fend off bracket seeking rocks
     
  Included 1350 pinion yoke provides increased strength over the stock companion flange.
     
  Super tough RockJock nodular iron front cover protects expensive internals and adds structural support to the housing's face flange
     
Powder Coat   Black satin powder coat finish adds long-lasting protection against rust and corrosion to keep your RockJock 44 looking its best

Notes

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

Pinion Yoke:  A larger stronger 1350 pinion yoke is included with the RockJock 44. If you wish to retain and reuse the stock driveshaft, you will need to remove the 1350 yoke and install the stock JK companion flange. The pinion nut torque specification is 125 ft-lbs

Outer Knuckle Assemblies: The RockJock 44 is designed to reuse the complete stock JK outer knuckle assemblies from the ball joints out (knuckles, hubs, disk brake calipers and rotors)

Overall Width: Axle width is 65.4 inches (stock JK width) between wheel mounting surfaces

Tire Size: Recommended maximum 37-inch tire size due to the inherent limitations of the stock brakes, wheel bearings, and axle u-joints
