Description
The ARB Air Locker Differential Dana 44A (Aluminum), Part #: arbRD226, is the ultimate traction solution for Jeep Grand Cherokee and Jeep Commander owners. Specifically designed for the Dana 44A (aluminum housing) rear axle, this air locker delivers maximum traction on demand with the reliability and performance ARB is known for.
The ARB Air Locker is pneumatically activated, providing 100% traction at the flip of a switch — even while moving. When engaged, it locks both axle shafts together to maximize traction in challenging off-road conditions. When disengaged, it operates like a standard open differential for smooth and predictable on-road handling.
Engineered for extreme reliability and minimal maintenance, the ARB Air Locker features a two-piece design with minimal moving parts. Its patented timed locking system ensures fast, reliable engagement and disengagement. The steel-reinforced elastomer-bonded annular seal is built to withstand the harshest temperatures and environments.
