ARB Air Locker 32-Spline Toyota 9.5-Inch Locking Differential for Select 1998-2021 Lexus/Toyota (RD152)

Fits 1998-2021 Toyota Land Cruiser and Tundra, and 1998-2007 Lexus LX470.

The ARB Air Locker RD152 provides 100% traction on demand, allowing you to bridge the gap between street drivability and off-road capability. This pneumatically operated locking differential replaces your vehicle's factory open differential, enabling you to lock both axle shafts together with the flip of a switch. By ensuring both wheels receive equal power regardless of ground resistance, the Air Locker maintains forward momentum in technical terrain without the tire scrubbing and driveline wear associated with permanent lockers.

Built for extreme durability, this 32-spline unit features a two-piece design with a patented timed locking mechanism for high strength and rapid engagement. The internal elastomer-bonded annular seal is engineered to withstand extreme temperature fluctuations, ensuring reliable pneumatic operation in the harshest environments. Whether you are navigating rock crawls or mud-slicked trails, the RD152 provides the control needed to drive in a slower, safer manner while protecting your drivetrain.
