About the Toyota 8" axle: the 8" solid front differential used on the Land Cruiser 70/80/105 Series is the same third-member family Toyota fits as the rear differential on many lighter models — light-duty Prado, 4Runner, Hilux and pickups/mini-trucks. This locker suits a wide range of Toyota 8" applications, front or rear; match the spline count (Toyota 8" fronts are typically 27 or 30 spline).
In the box: Air Locker differential, dash activation switch, solenoid valve, air line and bulkhead fitting. An ARB air compressor is required to operate (sold separately) — pair with an ARB CKMA12 (single) or CKMTA12 (twin).
