Built for the ARB RD146 Air Locker Differential for Toyota Tundra - Rear Axle, Steel Construction, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD146 Air Locker Differential is a top-tier traction aid designed to enhance off-road capability and on-road safety for Toyota Tundra models from 2012 to 2021. Featuring a pneumatically operated locking system, this differential allows you to switch between open and locked modes instantly with the flick of a switch, providing maximum traction when needed and seamless drivability on regular roads. Its robust steel construction ensures durability in demanding conditions, making it an ideal choice for serious off-road enthusiasts and professional drivers alike. When engaged, the Air Locker prevents internal gears from rotating independently, locking both wheels to the ring gear for optimal traction in challenging terrains. When disengaged, it functions as a conventional open differential, promoting smoother handling and reducing drivetrain wear. The ARB RD146 is engineered specifically for the rear axle of Toyota Tundra trucks with a 10.5-inch axle width, 1.44-inch shaft, and 36-spline configuration, ensuring a perfect fit and reliable performance. Its silver finish adds a sleek look while maintaining corrosion resistance for long-lasting use. This differential is suitable for all gear ratios within the specified fitment, providing versatility across different vehicle setups. Installation is straightforward for qualified technicians, and the product's steel build guarantees strength and longevity under demanding conditions. The ARB RD146 Air Locker Differential enhances vehicle control, safety, and off-road performance without compromising daily driving comfort or increasing driveline wear. Proper use of this differential can significantly reduce the risk of vehicle damage during extreme terrain navigation, while also minimizing environmental impact by enabling controlled, efficient driving in tough conditions. Manufactured by ARB, a trusted leader in off-road accessories, this differential is an essential upgrade for serious adventurers seeking reliability and top performance in their Toyota Tundra.
