Overview:

The ARB Air Locker M210 and M220 35Spline differentials are the ultimate traction solution for Jeep Wrangler (2018–2023) and Jeep Gladiator (2020–2023) models. Designed to deliver maximum traction on demand, the Air Locker allows drivers to lock the differential instantly with the flick of a switch, providing superior control and confidence in challenging off-road conditions. This advanced pneumatic locking system ensures both axle shafts turn together, eliminating wheel slip and enabling your vehicle to conquer the toughest terrain with ease.

Ideal for off-road enthusiasts and serious trail riders, the ARB Air Locker enhances vehicle capability without compromising on-road drivability. When disengaged, it functions as a conventional open differential, maintaining smooth handling and reducing driveline wear. This makes it a versatile upgrade for Jeep owners seeking reliable traction performance in all environments.
