The ARB Air Locker rear shim adjust component references a 30-spline configuration for Mazda 8-inch style applications and serves as part of ARB's locking differential systems. ARB lockers use a pneumatic mechanism to provide full traction on demand and include necessary activation hardware in their kits. These parts integrate into the locker installation and ARB notes an air compressor is required for operation, sold separately.
