ARB Ford 9-inch Rear Air Locker Differential, 31 or 35-spline SKU: 8731

ARB Air Locker Differential 9"
Quiet smooth operation on the road with no adverse affects on tires or handling. When you get to the ruff stuff just hit the switch and now you have a fully locked front end, rearend or both. The ARB air locker has been around over 15 years. They have been tested at about every hard-core wheeling spot on the earth and have proven their performance and reliability. So how does it work? Hit the switch and in one tenth of a second compressed air actuates a piston inside the differential which engages a locking gear, instantly locking the differential and directing torque to both driving wheels. Once you get through the hard spot just hit the switch and the diff. lock is disengaged.
