Rákerestem, valóban volt levegős zár is. Ma is újat tanultam. Azt írják az egyik fórumon, hogy:

Mitsubishi's factory locker is an air locker but it is slow to operate as it doesn't store the air for a quick activate and you need to wait for air pressure to build up to engage it, but is a good unit.

Egy másik helyen meg egy listát is a hátsó levegős diffivel érintett típusokról:

Some Mitsubishi Montero/Pajero's came with factory fitted rear differential air lockers
- 1994 to 1998 Montero 'SR' Model with 3.5 DOHC V6 came with factory locker
- 1998 to 2001 Montero Sport Model - Only a few of them. I've only seen/heard of two. Ever.
- 1992 to 1998 JDM Pajero SWB/LWB - 50% of them (guesstimate) came with factory fitted rear locker.

A Montero meg ugye a Pajero neve Amerikában, Indiában, Spanyolországban stb.
