ARB Air Locker — Mitsubishi IFS (28-Spline)
An open front differential quits the moment a wheel unloads on a climb or side-slope. The ARB Air Locker for the Mitsubishi IFS diff adds a driver-selectable, air-operated lock so both wheels on the axle drive together on command, then releases for normal steering and open-diff road manners.
This carrier is machined for the 28-spline Mitsubishi IFS differential used in the Mitsubishi Mighty Max, Montero and Raider (and in some vintage Ford F-100/F-150 applications sharing the diff). On-demand engagement gives you a fully committed axle only when the terrain calls for it, with no everyday driving penalty.
- Selectable, air-operated 100% differential lock
- Forged internals for the 28-spline Mitsubishi IFS diff
- Instant engagement from an ARB air source
- Bolt-in replacement for the factory carrier
Trade-off: requires a compressed-air supply and professional installation with correct differential setup.
