Extreme 60 High-Pinion Features

• Extreme 60 high-pinion nodular iron center section is simply the strongest 60 series casting we offer, with thicker walls and webbing to deliver superior strength and rigidity.
• 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 the gear begins to deflect under high torque loads.
• Extreme 60 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 60 housings.
• Replaceable AR400 hardened steel skid plate resists deformation and gouging to slide over obstacles far better than iron housings or mild steel plates.
• 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.
• 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 Advantek 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.
• Super strong Currie 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.
• 14.250 in. 8-lug vented rotors and OE Gladiator truck dual-piston calipers provide the power required to stop your JL, without the cost or availability issues of exotic brakes.
• Black satin powder coat finish adds long-lasting protection against rust and corrosion to keep your Extreme 60 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 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, click HERE.
• 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 (+2 inches over JL Rubicon) 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 or Synergy Manufacturing Track Bar bolt. 
• 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
