Closer Look
The ARB Air Locker is a driver-controlled, selectable locking differential specifically engineered for your Toyota 10.5 inch Rear Axle with 36 splines. It provides ultimate traction on demand without sacrificing on-road driveability.
A standard 'open' differential is a compromise, designed to allow wheels to turn at different speeds on pavement. Off-road, this becomes a liability, as it directs all power to the wheel with the least grip, leaving you stranded. While a limited-slip differential (LSD) offers a partial improvement, it requires wheelspin to engage and never truly locks. The ARB Air Locker for your 10.5 inch rear axle overcomes this by solidly locking the axle at the flick of a switch, providing 100% traction instantly.
This allows you to confidently tackle steep inclines, rocky obstacles, and slippery tracks. When disengaged, the Air Locker functions just like an open differential, maintaining safe and predictable handling on sealed surfaces. Built in Australia from high-strength, aerospace-grade materials, this ARB Air Locker is the durable and reliable traction aid trusted by off-roaders globally for its proven performance in Toyota 10.5 inch rear axles.
