Ultimate Traction for Ford Heavy-Duty Axles

Dominate the toughest trails and worksites with the ARB Air Locker, the world's premier traction aid engineered specifically for the Ford 10.25 and 10.5-inch rear differentials. Designed for 35-spline axle shafts, this pneumatic locking differential provides 100% traction on demand, ensuring you never get stuck in mud, sand, or uneven rocky terrain.

Technical Performance and Benefits

• Instant Engagement: Flick a switch to lock your differential instantly, regardless of speed or terrain conditions.
• Dual-Mode Operation: Functions as a standard open differential for smooth on-road driving and a fully locked unit for maximum off-road grip.
• Robust Construction: Engineered with high-strength materials to withstand the heavy torque demands of Ford E-Series and F-Series trucks.
• Pneumatic Reliability: The internal locking mechanism uses air pressure to force the differential gears to lock, tying both wheels directly to the ring gear rotation.

By preventing independent axle shaft rotation, the ARB Air Locker ensures that power is delivered to both wheels equally, maximizing your vehicle's capability. Whether you are hauling heavy loads or navigating technical off-road obstacles, this upgrade provides the confidence you need.
