ARB Air Locker Shim Kit

The ARB Air Locker shim kit is used to set up an ARB Air Locker air-operated locking differential. It helps you adjust the differential's internal spacing and gear mesh during installation, so the locker works correctly with the ring and pinion.

Key Features:

• Made for use with ARB Air Locker differential installations
• Shims let you fine-tune differential spacing and setup
• Sold under ARB's Air Locker line, which is widely used for off-road and 4x4 builds
• Several kit options cover different Air Locker applications

ARB is a well-known name in 4x4 and off-road equipment, and its Air Locker is a popular selectable locker. A shim kit lets the installer set the differential up carefully so it runs smoothly and reliably. Choose the kit option that matches your Air Locker and differential application.
