Overview:
The ARB Air Locker is the world’s leading traction aid designed to provide maximum grip and control in challenging driving conditions. Engineered for serious off-road enthusiasts and professionals alike, this pneumatically operated locking differential delivers instant, on-demand traction with the simple flick of a switch. Compatible with Dana 60 axles featuring 32 splines and gear ratios of 4.56 and up, the Air Locker is an ideal upgrade for classic muscle cars like the Dodge Charger and Challenger, as well as heavy-duty trucks such as the Dodge Ram 2500 and 3500.
By locking the axle shafts together, the Air Locker ensures both wheels turn at the same speed, preventing wheel slip and maintaining forward momentum on slippery or uneven terrain. When disengaged, it functions as a conventional open differential, preserving smooth on-road drivability and minimizing drivetrain wear. This versatility makes it perfect for drivers who demand superior traction without sacrificing everyday usability.
