ARB RD129 Air Locker for Toyota 8-Inch 12-Bolt 30-Spline (Select 1995-2015 Toyota Tacoma & Tundra)
$1,299.95
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1995-2015 Toyota Tacoma and 2000-2007 Toyota Tundra models. This ARB Air Locker RD129 provides 100% traction on demand, allowing you to lock your differential with the flick of a switch to conquer technical off-road terrain without compromising on-road drivability.
Built with a high-strength two-piece design, this differential uses a pneumatically operated locking system. When engaged, it prevents the internal gears from rotating, ensuring both axle shafts turn at the same speed as the ring gear. The patented "timed" locking mechanism ensures ultra-fast engagement and disengagement at any speed, while the steel-reinforced elastomer bonded annular seal is engineered to withstand extreme temperatures and harsh environments.
- Manufacturer Part Number: RD129
- Carrier Type: Toyota 8-Inch (12-Bolt)
- Axle Spline Count: 30
- Includes: Air Locker differential, activation switch, solenoid valve, air line, and bulkhead fitting
- Operation: Pneumatic (Requires air compressor, sold separately)
- Construction: Durable two-piece design with minimal moving parts for maximum reliability
