The Extreme 60 axles for 2007 thru 2018 Jeep JK Wrangler 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 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 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 13.25-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 Stabel 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 vehicles 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
heel 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: Axle width is 70 inches 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 8806-0
