ARB Air Locker Differential Shim Kit

The ARB Air Locker Differential Shim Kit line offers replacement carrier bearing pre-load shims for ARB Air Locker air-actuated locking differentials. Use these shims when you install, rebuild, or service a shim-adjusted differential. They help you set correct carrier bearing pre-load and proper differential setup.

Key Features:

• Replacement shim kits made for ARB Air Locker differential assemblies
• Help you reach the correct carrier bearing pre-load during installation and service
• Steel shim construction built for durable, repeatable performance
• Made by ARB, a name known for 4x4 drivetrain and off-road equipment
• Backed by ARB's 3-year warranty

Correct carrier bearing pre-load matters in any differential. Too little pre-load can lead to early bearing wear, ring and pinion damage, and oil or air leaks in an Air Locker differential. A fresh, correctly sized shim kit makes setup or a rebuild more accurate and reliable. Choose the child item that matches your differential and Air Locker model.
