Description
The ARB RD129 Air Locker is the ultimate traction solution for the rear axle of Toyota Tacoma trucks equipped with the 8.4-inch differential. Featuring a rugged two-piece steel design, it locks both axle shafts together at the flick of a switch, delivering instant 100% traction when needed to conquer tough off-road terrain.
The pneumatically operated locking system inside the differential prevents internal gears from rotating independently, ensuring both wheels turn in unison for maximum grip. When not engaged, the Air Locker acts like a standard open differential for smooth on-road handling.
Designed for durability and ease of use, the ARB Air Locker allows activation at any speed without driveline damage, giving you confidence in both rough terrain and everyday driving. The kit includes everything necessary for installation except the air compressor, which is sold separately.
Key features include:
- 100% traction on demand without impacting drivability or wear
- Simple driver-operated switch for seamless terrain adaptation
- Ultra-strong two-piece steel construction with minimal moving parts
- Patented timed locking mechanism for rapid engagement and release
- Elastomer bonded steel seals engineered for extreme temperatures
