Description
Conquer challenging terrain with the ARB RD149 Air Locker, engineered for Nissan M226 rear axles featuring 32 spline shafts and 10 bolt ring gears. This top-tier air locker delivers instant 100% traction at the flick of a switch, empowering you to tackle the toughest off-road conditions while maintaining smooth, reliable on-road performance.
The locker uses a pneumatic locking system that locks both axle shafts to the ring gear, preventing internal gears from rotating independently and ensuring maximum grip. When disengaged, it functions like a standard open differential for safe and controlled driving on pavement.
Built from tough two-piece steel, the RD149 offers exceptional durability and reliability with minimal moving parts. Its patented timed locking mechanism provides fast, strong engagement and quick unlocking, while the steel-reinforced elastomer bonded annular seal withstands extreme climates.
The complete kit includes the Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting. An air compressor (sold separately) is required for operation.
