The ARB 6mm pressure supply upgrade kit replaces thinner tubing with a 6mm polymer airline and push-in fittings that click into place, providing a stronger, more abrasion-resistant supply line. Bulkhead fittings can be configured as straight or 90-degree connections, and the kit retrofits existing Air Locker systems to a common 6mm pneumatic standard for improved fitment and durability.
