The ARB Air Locker RD82 turns the popular Ford 8.8" axle (28-spline) into a fully locked differential the instant you need it. A dash-mounted switch engages 100% lock for climbing, mud, sand and rock; disengage and the axle drives like a factory open differential, keeping road manners tame and tyre wear even.
The 8.8-inch Ford housing is one of the most common rear axles on the trail, appearing under many Ford F-150, Ranger, Explorer and Expedition models. ARB's forged four-pinion centre is built to survive big tyres and added horsepower, and air-operated engagement means locking is instant, repeatable and completely under your control.
