RockJock 44 - Jeep JK Rubicon Replacement Front Housing

The RockJock® 44 heavy-duty high pinion front housing is a direct replacement for the factory Jeep JK Rubicon unit (accepts stock Rubicon internals). With its strong reinforced center section, large diameter, thick wall tubes, and massive forged knuckles the RockJock 44 housing is twice as strong as the stock factory unit. Overall swap cost can be minimized by retaining and reusing the stock Rubicon internals or can be upgraded using any Rubicon compatible aftermarket parts.
SKU: JK-44HPF1
$2,080.00
PROP 65 WARNING:

Built to the legendary Currie Standard with features including:

  • RockJock 44 high-pinion nodular iron center section with thicker walls and webbing to deliver superior strength and rigidity 
  • Large 3” diameter .375” thick wall axle tubes that are more than twice as strong as stock
  • RockJock heavy duty forged inner knuckles, designed for use with up to 37” tall tires
  • The RockJock 44 weighs 134 lbs, compared to the stock Rubicon 44 front housing at just 91 lbs.
  • Upper control arm mounts feature rebuildable Johnny Joints® for improved suspension articulation
  • Lower control arm mounts are one-piece construction with integrated skid plates to help fend off bracket seeking rocks

 

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

The Currie RockJock® high pinion 44 is an all-new, heavy-duty 44 made 100% by Currie. Our casting is a heavy duty, ductile iron piece that uses the larger JK high pinion 44 gears only. These gears feature a larger ring gear than a standard 44 as well as a 29 spline Dana 60 size pinion gear. Tubes are 3" x .375" wall. All new heavy-duty JK suspension brackets are mounted on this housing for an easy bolt in installation; all holes are drilled and threaded where applicable for factory reuse of the JK Rubicon's electric locker and Currie's forged JK knuckles are installed. These are completely custom-built units that are made-to-order to each customer's specifications and application. They provide a much stronger assembly than the factory frontend in Jeep JK vehicles. NOTES: Unit is the factory 65.400" overall finished width. This housing weighs 134lbs. Where a stock JK high pinion 44 front housing weighs 91lbs. Housings do not include ball joints, cover or yoke.
