Fitment: Toyota Land Cruiser 100/105/200 Series Rear (9.5" 32-Spline). Toyota 9.5" (12-bolt, full-float), 32-spline, all ratios. 12-bolt 9.5" full-float rear, 32-spline — also Lexus LX470/LX570.
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).
