Description

The ARB Air Locker RD114 is a differential designed to keep vehicles moving in all conditions by providing instant lock at any moment. It operates like a conventional open differential when unlocked, and when activated, it prevents the internal differential gears from rotating, ensuring maximum traction. It is compatible with GM Full Float 14B 10.5 inch rear axles with a 1.56 inch shaft and 30 splines. All gear ratios are supported, but 4.56 and up ratios must use a 'thick' gear.
