The ARB RD136 Air Locker is the ultimate selectable traction aid for Nissan vehicles equipped with the H233B rear axle and 31-spline shafts. Designed for serious off-road use, this locker provides 100 percent traction on demand with the flip of a switch—no need to stop or leave the driver's seat.
Using a pneumatically actuated locking system inside the differential, the RD136 instantly locks both axle shafts together to eliminate wheel spin in low-traction situations. When unlocked, it operates as a standard open differential for normal driving. The rugged two-piece design and minimal moving parts offer unmatched strength and reliability, while the steel-reinforced elastomer seal stands up to extreme temperatures.
Perfect for demanding off-road terrain from Utah’s slickrock to muddy forest roads, this Air Locker transforms your Nissan into a true trail machine.
Note: Requires air compressor (sold separately). Must use 50mm ID carrier bearings (part number 160116) for optimal bearing life.
