ARB RD132 Toyota 8 inch 4cyl and V6 Air Locker

This ARB RD132 Toyota 4cyl and V6 Air Locker is one of the world’s most highly regarded traction aid. The ARB Air Locker is a driver controlled locking differential originally designed to give serious 4 wheelers the traction needed to combat extreme off road terrain. When extra traction is required, the driver activates the Air Locker via a convenient dash mounted switch. Pneumatic pressure supplied by an on board air compressor engages ARB’s patented locking mechanism within the Air Locker, thus preventing the wheels from turning independently. The Air Locker is deactivated by flicking a switch, returning the differential to normal. By far the most coveted locker in the world! Choose from front or rear lockers.

The RD132 Superceeds the RD23 in March of 2007.

If you have a 4cyl differential, late model 50.00mm [1.969"] id carrier Bearings must be used. (ARB Part No. 160116)
