Built for the ARB RD173 Air Locker Differential for Ford F-350 Super Duty and E-350 Models, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD173 Air Locker Differential is a high-performance traction aid designed to enhance off-road capability and vehicle control in challenging terrains. This pneumatically operated locking system allows you to instantly engage full locking at the flick of a switch, providing 100% traction on demand without sacrificing on-road drivability. Constructed from durable steel, the ARB Air Locker is engineered to withstand the toughest conditions while maintaining smooth operation and reliability. When activated, it prevents the internal differential gears from rotating independently, effectively tying both wheels to the ring gear for maximum traction. This feature is especially beneficial when navigating steep inclines, loose gravel, mud, or snow, where maintaining traction is critical for safety and performance. When disengaged, it operates like a conventional open differential, providing normal handling and reducing driveline wear during regular driving. This versatility ensures your vehicle remains adaptable for both daily driving and demanding off-road adventures, reducing potential damage and environmental impact.
This model is compatible with several Dana axles, including the Dana 70 and Dana 80, with various ratios and spline configurations suitable for rear and front axles. Its installation fits models like the Ford F-350 Super Duty from 2012 to 2016 and Ford E-350 Super Duty from 1999 to 2003. The ARB RD173 features a sleek silver finish, offering both durability and aesthetic appeal. Designed for ease of use, it allows drivers to switch between unlocked and locked modes instantly, providing enhanced control and confidence in extreme conditions. Whether you’re tackling rugged trails or improving the traction of your heavy-duty truck, this ARB Air Locker ensures your vehicle can handle the toughest terrains with ease, making it a valuable addition to your off-road gear. Proper installation and compatibility with your axle specifications are essential for optimal performance and safety. Always follow manufacturer guidelines for installation and operation to maximize the benefits of this premium differential locking system.
