ARB RD90 Air Locker for 1984-2006 Toyota 4Runner/Pickup/Tacoma/Tundra 7.5" IFS 27-Spline 10-Bolt

Fits select 1984-2006 Toyota 4Runner, Pickup, T100, Tacoma, and Tundra models with 7.5" IFS (27-spline).

The ARB RD90 Air Locker is the industry standard for selectable traction, allowing you to lock your front differential with the flick of a switch. When engaged, the pneumatic system locks the internal gears to prevent the axle shafts from turning independently, ensuring 100% of available torque is sent to both wheels. This provides maximum traction in technical off-road conditions without compromising the on-road drivability of a conventional open differential.
