Built for the ARB RD81 Air Locker Differential for Ford 8.8 in Rear Axle, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD81 Air Locker Differential is the ultimate traction solution designed for demanding off-road conditions. Crafted from durable steel, this pneumatic locking differential allows you to instantly engage maximum traction at the flick of a switch, ensuring continued movement across challenging terrains. Its innovative design prevents internal differential gears from rotating independently, effectively locking the axle shafts together and maintaining optimal contact with the terrain. When disengaged, it operates as a standard open differential, providing smooth and predictable on-road handling. The ARB Air Locker enhances vehicle control, reduces the risk of damage, and minimizes environmental impact by enabling safer, more controlled driving in difficult conditions.
This model is specifically designed for Ford 8.8-inch rear axles with a 1.32-inch shaft diameter, 31 spline configuration, and fits a range of vehicles including Ford Explorers from 2001 to 2014 and Ford E-150 models from 2003 to 2014, as well as select Mazda B4000 trucks from 1994. Its robust steel construction ensures longevity and reliable performance under tough conditions. The Silver finish adds a sleek look to your axle assembly while providing corrosion resistance. Installation is straightforward for experienced mechanics, and the differential’s design supports activation at any speed, allowing for seamless transitions between unlocked and locked states.
Designed for off-road enthusiasts and professional applications, this Air Locker Differential offers 100% traction on demand, helping you conquer mud, snow, rocks, and other hazardous terrains with confidence. Its compatibility with a variety of Ford and Mazda models makes it a versatile upgrade to enhance your vehicle’s capabilities. Whether navigating rugged trails or recovering from unforeseen obstacles, the ARB RD81 provides the dependable performance necessary to keep you moving forward.
