Notes

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

Computer Programming: 2012 and newer vehicles require a computer programmer to reset the gear ratio and tire height in the vehicle's computer for the proper function of the vehicles stability control system

Driveshaft: A replacement driveshaft compatible with the larger 60 housing and 1350 yoke is required. Spicer PN 10113216 is recomended (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 trac 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

Differential Carriers: Carriers provided by Currie for the Extreme 60, are turned down to 8.300" O.D. for load bolt clearance. If a standard O.D. carrier is installed the load bolt will need to be backed out to prevent damage
