Front air locking differential – Land Rover – HF (RD128)
The HF rear air locking differential – part number RD128 is designed for enthusiasts of extreme off-roading, rock crawling, raids, and expeditions. This system allows you to fully lock the rear differential on demand, thus ensuring optimal engine torque distribution between the rear wheels.
This kit makes your Toyota more capable in terms of traction in the most difficult conditions (deep mud, slippery surfaces, rocks) and improves the control, safety, and overall grip of the vehicle.
🚀 Main advantages
🔹 Optimized traction
Locking the rear differential distributes torque equally between both wheels, reducing wheel spin and improving grip even on uneven terrain.
🔹 Increased control
In extreme situations, the locker offers the driver better vehicle stability and control, which is essential for technical maneuvers.
