The standard 5mm blue airline supplied with ARB Air Lockers can become brittle and fail, especially when exposed to heat from the exhaust or abrasion on tough tracks. A cracked or split airline will leak air, preventing your diff lock from engaging and leaving you without traction when you need it most. This 6mm black line upgrade kit is a preventative measure to replace the weaker original line that runs from the solenoid to the differential bulkhead fitting, ensuring your lockers work every time.
This is a universal upgrade kit. Please check your existing ARB Air Locker setup to confirm compatibility. Please contact us with your VIN details if you require further assistance to confirm fitment.
