Built for the ARB RD128 Air Locker Differential for Land Rover – Front and Rear Axle Traction Locking System, this ARB component delivers rugged durability, precise fitment, and trail-ready performance. Engineered for serious off-road use while maintaining everyday drivability.
The ARB RD128 Air Locker Differential is a premium traction enhancement device designed specifically for Land Rover models, including Discovery and Defender vehicles. This pneumatically operated differential provides instant lock capability at the flick of a switch, ensuring maximum traction in challenging off-road conditions. Its robust steel construction guarantees durability and reliable performance when tackling tough terrain. When activated, the Air Locker prevents the internal differential gears from rotating independently, forcing both wheels on an axle to turn together, which significantly improves grip and stability during off-road adventures. When disengaged, it operates as a conventional open differential, maintaining smooth on-road driving and minimizing driveline wear. This feature allows drivers to switch seamlessly between normal driving and aggressive off-road modes, reducing the risk of vehicle damage and environmental impact by maintaining optimal traction control. The ARB RD128 fits front and rear axles with a 1.24-inch shaft diameter, 24 spline, and a 3.54 ratio, ensuring compatibility with a range of Land Rover models from 1993 to 2004. The differential’s steel construction ensures longevity and resistance to harsh conditions. As a critical component for off-road enthusiasts and professional drivers, this Air Locker Differential enhances vehicle capability across diverse terrains while preserving on-road drivability. Installation requires no special modifications, making it a practical upgrade for improved traction and vehicle control in demanding environments. Properly maintained, the ARB RD128 offers consistent performance, helping drivers confidently navigate mud, snow, rocks, and uneven surfaces with reduced wheel slip and increased safety.
