ARB RD146 Air Locker Rear Differential for Select Toyota Tundra 2007-2021 and Land Cruiser (10.5in, 36 Spline)

Fits select 2007-2021 Toyota Tundra and 2020-2021 Toyota Land Cruiser models with the 10.5-inch rear differential.

The ARB Air Locker RD146 is the industry-leading solution for selectable traction, allowing drivers to switch from a conventional open differential to a fully locked 100% traction aid with the flick of a switch. This pneumatically operated system uses an internal locking mechanism to prevent axle shafts from turning independently, ensuring both wheels maintain equal rotation for maximum grip in sand, mud, or rocky terrain. Unlike automatic lockers, the Air Locker has no impact on on-road drivability or tire wear when disengaged.

Engineered for extreme durability, this two-piece differential features a steel-reinforced, elastomer-bonded annular seal designed to withstand severe temperature fluctuations. The patented timed locking mechanism provides high-strength engagement and ultra-fast unlocking for precision control on the trail.
