Currie Extreme 60 - Jeep Wrangler JL Axle Assemblies

The Extreme 60 axles for 2018 and newer Jeep Wrangler JL are complete bolt-in axle assemblies with all required brackets and mounts in place. The vehicle's factory driveshafts will require modification or replacement to accommodate the larger 1350 series u-joint and 60 series housing

Extreme 60 Front Features
		Designed and optimized using computer simulation, the Extreme 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 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
		Massive forged 1-ton inner knuckles (right) are designed to stand up to severe off-road punishment and large tires without flinching
		Complete 1-ton outer steering assemblies deliver massive strength, while 14.25-inch diameter vented rotors and OE Jeep Gladiator dual-piston calipers provide the increased brake capacity required for stopping big tires
		Warn® premium manual locking hubs are the industry standard for durability and reliability
		Rock-proof 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
		UV Stable Satin black powder coat finish adds long-lasting protection against rust and corrosion to keep your Extreme 60 looking its best
Extreme 60 Rear Features
		Designed and optimized using computer simulation, the housing is reinforced with thicker walls and webbing and utilizes standard cut gears to deliver maximum strength, durability
		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
		Currie 40-spline full-floating chromoly axles are the largest in the industry and provide 1.5x the strength of 35-spline chromoly axles
		Desert race-inspired heat-treated Chromoly spindles with billet steel full-floating hubs carry the vehicle's weight, eliminating the influence of side loading and impact shock on axle durability. Modified OEM backing plates and parking brake assemblies provide reliable operation with broad availability of serviceable wear items
		13.750-inch vented rotors and OE Jeep Gladiator calipers provide the stopping power with factory pedal feel, while the 8-lug bolt pattern improves reliably with large, heavy tires
		Rock-proof Currie nodular iron cover protects expensive internals and adds structural support to the housing's face flange for increased rigidity
		UV Stable Satin black 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

Brake Upgrade: The big brake kit included with the Extreme 60 uses 14.250-inch rotors and Jeep Gladiator dual-piston calipers in the front and 13.75-inch vented rotors and Gladiator calipers in the rear to provide the stopping power required for large tires

Wheel and Tire Size: For proper brake caliper clearance, 17-inch or larger wheels are required. 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: Axles are offered in widths of 70 or 72 inches between wheel mounting surfaces. Additional width improves the frame and body clearance for large tires and provides additional space for coil-over shocks.

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
