ARB RD137 Air Locker Locking Differential - Kit

The ARB RD137 Air Locker is a selectable locking differential that provides maximum traction when you need it most. Recognized as the world's premier traction aid, ARB Air Lockers allow you to lock your differential on demand, delivering 100% power to both wheels for superior performance in challenging off-road conditions including mud, sand, rock, and snow.

Key Features:

• Pneumatic activation allows you to engage and disengage the locker from inside the cab
• Seamless operation on normal roads when unlocked, full traction when locked
• Forged steel internal components for maximum strength and durability
• Complete kit includes replacement differential housing, activation switch, solenoid valve, air line, and bulkhead fittings
• Proven design trusted by off-road enthusiasts and professionals worldwide

Unlike open differentials that send power to the wheel with least resistance, the ARB Air Locker ensures both wheels rotate at the same speed when engaged, preventing wheel spin and keeping you moving forward. The system requires an on-board air source for operation and integrates seamlessly with most air compressor setups.
