Built for the ARB RD114 Air Locker Differential for GM Full Float 14B Axles, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD114 Air Locker Differential is a premium traction aid designed to enhance off-road capability and on-road safety. Crafted from durable steel with a sleek silver finish, this differential provides instant locking with the flick of a switch, offering maximum traction in challenging terrains. Its pneumatically operated locking system ensures reliable engagement regardless of vehicle speed, allowing you to conquer steep inclines, loose gravel, mud, and snow with confidence. When activated, the Air Locker prevents the internal differential gears from rotating independently, tying both wheels directly to the ring gear for optimal power transfer and traction. When disengaged, it functions like a conventional open differential, ensuring smooth on-road driving without impacting driveline wear or vehicle handling. This makes it an excellent choice for drivers seeking versatile performance both on and off the road.
The ARB RD114 is specifically engineered for rear axles with a 1.56-inch shaft, 30 spline, and compatible with GM Full Float 14B 10.5-inch axles. Its robust steel construction guarantees longevity and performance under demanding conditions. Designed to fit a range of vehicles including various Chevrolet and GMC models from the early 1970s to modern trucks, this differential seamlessly integrates with your existing drivetrain system. Its straightforward installation and reliable operation make it an essential upgrade for off-road enthusiasts and professional drivers alike, providing 100% traction on demand and improving vehicle control in the toughest environments.
Safety and environmental considerations are paramount, and the ARB RD114 complies with Prop 65 standards, warning users of potential cancer and reproductive harm as required by law. Whether you're tackling rugged trails or enhancing your vehicle's off-road resilience, this ARB Air Locker Differential offers the performance, durability, and confidence you need to stay moving in all conditions.
