Built for the ARB RD140 Air Locker Differential for Rear Axle - 100% Traction on Demand, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD140 Air Locker Differential is the ultimate traction solution designed for rugged off-road adventures and challenging terrains. Crafted from durable steel and finished in a sleek silver, this differential provides instant locking capability with just the flip of a switch, ensuring maximum traction when needed. Its pneumatically operated locking system engages internal gears, preventing axle shafts from rotating independently and allowing both wheels to turn in unison for enhanced grip. When unlocked, it functions as a conventional open differential, maintaining on-road drivability and reducing driveline wear, which contributes to vehicle longevity and environmental safety. This versatility makes it suitable for a wide range of off-road conditions and driving styles, offering the driver control over traction as the situation demands. The ARB Air Locker is designed specifically to fit rear axles on various Ford Super Duty models, including F-250 and F-350 from 2012 to 2014, as well as certain E-Series trucks, ensuring reliable performance across different vehicle setups. Its robust steel construction guarantees durability under demanding conditions, while the simple pneumatic activation allows for quick engagement during critical moments. The ARB RD140 is a proven choice for off-road enthusiasts and professional drivers seeking a reliable, high-performance locking differential that enhances vehicle stability, traction, and safety in the toughest environments.
