Watch in action

Unmatched Traction with ARB Air Locker

When the trail gets tough, the ARB Air Locker is the ultimate tool to keep you moving. Engineered as the world's premier traction aid, this differential locker provides 100% lockup on demand, ensuring that both wheels receive equal power regardless of surface conditions. Whether you are navigating deep mud, loose rock, or steep climbs, the ARB Air Locker transforms your vehicle's off-road capability.

Key Features and Benefits

  • Instant Engagement: Pneumatically operated system locks the differential instantly.
  • Dual-Mode Operation: Functions as a standard open differential on-road and a locked unit off-road.
  • Robust Construction: Designed for AAM 9.25 and 9.50 axles with 33-spline shafts.
  • Reliability: Proven performance in the harshest environments globally.

The advantage of the ARB system lies in its simplicity and strength. By preventing internal gears from rotating, the Air Locker forces the axle shafts to turn in unison, maximizing traction. This is essential for classic Chevrolet and GMC trucks from the 1980s, including the C10, K10, and Suburban models equipped with AAM axles. Unlike limited-slip differentials that can fade or fail, the ARB Air Locker offers consistent, reliable performance every time you hit the switch. Enhance your rig's off-road prowess with high-quality drivetrain components from GGCRACING.

…and 105 additional fitments. Contact us to confirm yours.
