Description

The ARB RD146 Air Locker Rear Differential is designed specifically for Toyota Tundra owners seeking peak performance in any condition. With its innovative pneumatic locking system, this differential ensures maximum traction when needed, yet offers the convenience of disengaging for standard driving. This allows your vehicle's axle shafts to lock together, providing unbeatable traction where standard differentials falter, especially in challenging off-road environments.
