Maximum Traction for Toyota and Lexus

Take your off-road adventures to the next level with the ARB Air Locker, precision-engineered for the rear differential of the Toyota 4Runner, FJ Cruiser, and Lexus GX460. This is the ultimate tool for drivers who refuse to let terrain dictate their path, providing 100% traction at the touch of a button.

Engineered for Performance

  • On-Demand Locking: Engage the locker instantly to tackle mud, sand, or steep rocky inclines.
  • Seamless Integration: Designed specifically for the Toyota/Lexus rear axle housing for a perfect fit.
  • Durability: Built to withstand the high-torque demands of modern off-road vehicles.
  • Versatility: Enjoy the benefits of an open differential on the highway and a locked axle when the trail gets technical.

The ARB Air Locker replaces your factory differential with a pneumatically operated system that locks your axle shafts together. This ensures that both rear wheels receive equal power, preventing wheel spin and maximizing your vehicle's climbing ability. Whether you are driving a 2010 FJ Cruiser or a 2024 4Runner, this upgrade is essential for serious overlanding and trail riding. It provides the mechanical advantage needed to navigate challenging obstacles safely and effectively. When you need performance you can count on in the backcountry, choose the industry leader.
