Closer Look
The ARB Air Locker 32 Spline is a driver-controlled, selectable locking differential specifically engineered for the rear 8.9 inch axle of your Toyota Hilux and Fortuner. Providing ultimate traction on demand without sacrificing on-road driveability, this Air Locker, suitable for OE locker equipped vehicles, delivers equal drive to both rear wheels when activated, allowing you to take full advantage of available traction in all off road conditions.
Standard 'open' differentials compromise off road capability by directing power to the wheel with the least grip, leaving you stranded. While a limited-slip differential offers some improvement, it requires wheelspin to engage and never truly locks. The ARB Air Locker overcomes this by solidly locking the axle at the flick of a switch, providing 100 percent traction instantly to conquer steep inclines, rocky obstacles, and slippery tracks.
Built in Australia from high-strength, aerospace-grade materials, the ARB Air Locker is a durable and reliable traction aid trusted by off roaders globally. When disengaged, it functions like an open differential, maintaining safe and predictable handling on sealed surfaces, ensuring your Toyota Hilux or Fortuner is always ready for your next adventure.
