2005-2023 Toyota Tacoma | 2003+ 4Runner | 2007-2014 FJ Cruiser | 2005+ Hilux 8" Clamshell Air Locker - 30 Spline 3.73 & Down (RD121)

This ARB RD121 Toyota 8-inch Air Locker is one of the world’s most highly regarded traction aids. 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 onboard 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.
