ARB RD111 Air Locker Differential Toyota 8" IFS 30 Spline 3.91 & Up

The ARB RD111 is the world's premier traction aid, designed specifically for Toyota 8-inch IFS (Independent Front Suspension) applications with 30 spline axles and 3.91 and higher gear ratios. With the flick of a switch, this Air Locker provides instant locking at any moment, and its super-strong design allows activation at any speed, enabling you to conquer the most challenging off-road terrain.

How It Works:

The advantage of the Air Locker lies in its pneumatically operated locking system inside the differential. When activated, it prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential.
