H233B Air Lockers
Upgrade your Nissan H233B axle with an air locking differential designed to provide selectable, on-demand traction for off-road, 4x4, rock-crawling, and overland applications. When engaged, an air locker locks both axle shafts together so both drive wheels receive power even when one tire loses traction.
H233B air lockers are especially useful in rocks, mud, sand, loose dirt, steep climbs, and uneven terrain where an open differential can allow one wheel to spin. With the locker disengaged, the differential returns to normal operation for everyday street driving.
Air lockers require a compatible onboard air source and are commonly paired with an air compressor for reliable engagement. They are a popular upgrade for H233B-equipped Nissan trucks and SUVs running larger tires, deeper gearing, or other drivetrain modifications.
