Description
The ARB RD152 Air Locker is a premium, on-demand traction solution for Toyota vehicles equipped with a 9.5" rear axle and 32 spline axle shafts. Perfect for off-road enthusiasts and overlanders, this differential locker is engineered to provide 100% traction whenever you need it, without compromising drivability on pavement.
By engaging a switch from inside your cab, the Air Locker locks both axle shafts together to eliminate differential action and maximize grip. Unlike electronic traction control or limited-slip differentials, the Air Locker delivers true mechanical locking, ensuring reliable performance in mud, rocks, snow, or sand.
Its two-piece steel design offers exceptional strength with minimal moving parts, while the reinforced annular seal handles the most extreme temperature swings on Earth. The RD152 includes everything you need for installation with an ARB air compressor (sold separately): solenoid, switch, air lines, and bulkhead fittings.
Whether you're driving a Tundra with a 9.5" diff or a Land Cruiser/LX470, the RD152 is a proven upgrade for conquering tough terrain with confidence.
