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 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 Stabele 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 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 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
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
