ARB RD145 Air Locker Locking Differential

The ARB RD145 Air Locker is a selectable locking differential that provides maximum traction when you need it most. Unlike limited-slip differentials that can lose effectiveness over time, the Air Locker delivers 100% traction to both wheels on demand, allowing you to conquer challenging off-road terrain including mud, snow, sand, and rock.

Key Features:

• On-demand activation—engage only when needed for improved fuel economy and reduced tire wear during normal driving
• Pneumatic operation provides reliable, progressive engagement without the drawbacks of electronic systems
• Forged steel construction with hardened gears for exceptional strength and durability
• Proven design trusted by off-road enthusiasts and professional expedition drivers worldwide
• Complete kit includes replacement differential carrier, in-cab activation switch, solenoid valve, air line, and bulkhead fittings

The Air Locker installs in place of your factory differential carrier and connects to your vehicle's compressed air system or an on-board air compressor. When activated, compressed air engages the locking mechanism to lock both axle shafts together, ensuring equal power distribution to both wheels. When disengaged, the differential operates like a standard open differential for smooth, quiet on-road driving.
