Watch in action

Unmatched Off-Road Performance for Toyota Trucks

Take control of your vehicle's traction with the ARB Air Locker, designed for the 12-bolt, 30-spline Toyota 8-inch differential. This industry-leading traction aid is the perfect upgrade for Toyota Tacoma and Tundra owners looking to tackle extreme off-road obstacles. With a simple press of a button, you can engage the pneumatic locking mechanism, effectively locking your differential to ensure both wheels spin at the same speed, providing maximum grip in even the most treacherous conditions.

Why Choose ARB Air Lockers?

  • Instant Engagement: Provides immediate locking power when you need it, and unlocks instantly for smooth on-road cornering.
  • Superior Durability: Built with high-strength components to handle the rigors of heavy-duty off-roading.
  • Versatility: Allows for a slower, safer approach to technical obstacles, reducing the need for high-speed momentum.
  • Seamless Integration: Designed to replace the internal differential gears without compromising the integrity of your factory housing.

The ARB Air Locker is the gold standard for off-roaders who demand reliability and performance. By preventing the internal differential gears from rotating, it forces the axle shafts to turn in unison, eliminating the wheel spin that often leads to getting stuck. When unlocked, it operates as a standard open differential, ensuring your truck remains comfortable and safe for daily driving. Trust your drivetrain needs to the experts at GGCRACING.
