ARB Air Locker Dana 60 HD Locking Differential (4.10 & Down) - RD167 - Fits Select Chevrolet, Dodge, Ford, and GMC 1968-2014

Fits select 1968-2014 Chevrolet, GMC, Dodge, and Ford vehicles equipped with a Dana 60 HD axle (4.10 and numerically lower gear ratios).

The ARB Air Locker RD167 provides 100% traction on demand, allowing you to tackle technical terrain with confidence. This pneumatically operated locking differential replaces the factory open carrier, giving you the ability to lock both axle shafts together via a dash-mounted switch. When engaged, the internal gears are prevented from rotating, ensuring maximum power is delivered to both wheels regardless of surface conditions. When disengaged, it operates as a standard open differential for smooth street drivability.

Designed for professional-grade durability, the RD167 features a two-piece construction with minimal moving parts to maximize reliability. The internal annular seal is elastomer-bonded and steel-reinforced to handle extreme temperature ranges and high-pressure pneumatic cycles without failure. A patented timed locking mechanism ensures rapid engagement and fast unlocking when returning to paved roads.
