The Extreme 60 high-pinion axle for 2007 thru 2018 JK/JKU 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 60 series housing and 1350 series u-joint

 

Extreme 60 High-Pinion Features

 

  Designed and optimized using computer simulation, the Extrem 60 is reinforced in critical areas with thicker walls and heavier webbing to deliver maximum strength, durability, and rigidity
   
  The front high-pinion radius bottom center section with a replaceable skid plate delivers unmatched ground clearance and improves obstacle slide-over by presenting a smooth curve
     
  Large 3.5 in. diameter x .375 wall axle tubes (left) are more than two times stronger than the stock axle tubes (right) without being overweight or sacrificing ground clearance
   
  High volume flow-thru recirculating oil system keeps pinion bearings bathed in cool oil, reducing operating temperatures and eliminating oil starvation issues
   
  Front axle steering geometry is optimized for large tires and lifted vehicles with increased caster and pinion angles
   
  The included heavy-duty tie rod features a 1.375 in. OD x .375 wall heat-treated chromoly tube and 1-ton forged rod ends that are designed to withstand off-road abuse and large tires
   
  Currie Extreme forged 1-ton inner knuckles (right) are designed to stand up to severe off-road punishment and large tires without flinching
   
  14.250 in. 8-lug vented rotors, and OE Gladiator truck dual-piston calipers provide the power required to stop your JK without the cost or availability issues of exotic brakes
     
  Warn®premium manual locking hubs are the industry standard for durability and reliability
     
  Currie rock-proof 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
     
Powder Coat   Black satin powder coat finish adds long-lasting protection against rust and corrosion to keep your Extreme 60 looking its best

 

 

Notes

ABS Sensors: Axles do not include ABS sensors; the factory sensors from the stock axles must be retained and installed on the Extreme 60 front and rear axle assemblies

Computer Programming: A programmer is required to reset the gear ratio and tire height settings in the vehicle's computer for the proper function of the vehicle's stability control and transmission shift points when larger than stock tires are installed

Driveshaft: A replacement driveshaft compatible with the larger 60 housing and 1350 yoke is required. Spicer PN 10113216 is recommended (verify manufacturer vehicle fitment)

Wheel and Tire Size: 17-inch or larger wheels are required for proper clearance of the brake calipers. Wheels must have a 4.9-inch (125 mm) hub bore with a recommended 4.5-inch backspace. The maximum recommended tire size is 42 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: The Extreme 60 Ram assist bracket requires an aftermarket stud-style track bar bolt to accommodate a steering stabilizer. Trac bar bolts are available from FOX Racing P/N 803-02-028 or Synergy Manufacturing P/N 8806-01
