Differentials & Lockers

Locking differentials send drive to both wheels on an axle, so one tire in the air or on ice no longer stops you. This collection is built around the ARB Air Locker — an air-actuated locker you engage from the cab and run as a normal open diff the rest of the time — in fitments for most common axles, from Toyota 8-inch and Ford 8.8 to Dana 60, Chrysler 8.25, and AMC Model 20.

Alongside the lockers you'll find diff rebuild kits, seals, and hardware. Air Lockers need compressed air to engage, so budget for an onboard air compressor if you don't run one, and confirm your axle's spline count and gear ratio before ordering.
