Fitment: Toyota Land Cruiser 40/60/70/80 Series Rear (9.5" 30-Spline). Toyota 9.5" (12-bolt, 30-spline; full & semi-float), 30-spline, all ratios. The ONLY rear locker that fits the early 40/60/70 semi-float 27-spline C-clip axle (Eaton E Locker won't).

Ring-gear sizing: Toyota rear differentials quoted as 8.9-inch and 9.5-inch are frequently used synonymously — the meaningful difference between Toyota rear diffs is usually the spline count (27, 30, 32 or 36 spline), not the nominal ring-gear size. Match your axle by spline count / axle code rather than the quoted size before ordering.

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).
