Description
The Currie Extreme 60 1-Ton Front and Rear Axle Assemblies are purpose-built for Jeep Gladiator owners pushing into the most demanding off-road environments. Engineered to handle up to 42-inch tires and V8 horsepower, these axles are designed for extreme rock crawling, high-speed desert use, and technical terrain where failure is not an option.
At the core of the Extreme 60 is Currie’s reinforced center casting, featuring thick walls and heavy webbing to maximize gear strength and long-term durability. The front axle is equipped with complete 1-ton inner and outer steering components, while the rear axle utilizes 40-spline shafts and billet full-floating hubs to deliver unmatched reliability under extreme load.
The high-clearance front center section includes a rotated cover with an integrated low-friction skid plate, improving obstacle clearance and allowing the axle to slide smoothly over rocks and ledges. Massive vented brakes at all four corners provide confident stopping power for heavy, high-horsepower builds, while the 8-lug wheel bolt pattern ensures maximum strength and component longevity.
Available as front only, rear only, or a matched front and rear set, the Currie Extreme 60 axles can be configured with your choice of selectable locker and gear ratio, making them a true turnkey solution for extreme Gladiator builds.
If your adventures take you to the most punishing trails and obstacles, the Currie Extreme 60 axles are built to go further—and come back intact.

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 radius bottom center section with replaceable AR400 skid plate delivers unmatched ground clearance and improved obstacle slide-over
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 upgraded 1350 pinion yoke provides increased strength and reliability over the failure-prone factory CV Joint
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 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
Lower control arm mounts are one-piece construction with integrated skid plates to help fend off bracket-seeking rocks
UV Stable Satin black powder coat finish adds long-lasting protection against rust and corrosion to keep your Extreme 60 looking its best
