ARB 060108SP Air Locker Long Cross Shaft 15.5mm Replacement SP Part

The ARB 060108SP is a genuine OEM replacement long cross shaft designed for use in ARB Air Locker locking differentials. With a 15.5mm shaft diameter, this long-style cross shaft is a direct-fit service part engineered to restore your Air Locker differential to factory specifications.

The cross shaft is a critical internal component within the ARB Air Locker's spider gear assembly. It supports the pinion gears inside the differential carrier, transmitting torque between the side gears under both open and locked conditions. Replacing a worn or damaged cross shaft with a genuine ARB SP (spare parts) component ensures proper fit, correct material grade, and long-term reliability.

Key Features:

• Genuine ARB OEM replacement spare part (SP series)
• 15.5mm diameter — long shaft configuration
• Precision machined to ARB factory tolerances for direct fitment into compatible Air Locker differentials
• Manufactured from high-strength alloy steel to withstand the demanding forces inside a locking differential
• Part of ARB's comprehensive Air Locker service parts program

This cross shaft is compatible with select ARB Air Locker differential models that use the 15.5mm long cross shaft specification. Always verify compatibility with your specific ARB Air Locker part number (RD-series) before ordering. Refer to your ARB Air Locker parts list or consult an ARB dealer to confirm fitment for your application.
