ARB AIR LOCKER LOCKING DIFFERENTIAL KIT -- 28-spline, supports 2.73/1 ratio, 5 in. ring gear ID, 10 x 6.14 in. ring bolt pattern; Includes a pneumatically-operated differential, an air line, a solenoid valve, an activation switch and bulkhead fittings; Unlike regular differentials that cause your vehicle to lose traction on rough terrain, the Air Locker utilizes a separately-sold 12-volt on-board air compressor to lock its differential gears and provide 100 percent off-road traction at the flick of a switch; This feature also reduces the likelihood of vehicle damage and environmental impact since an Air Locker-equipped truck relies less on momentum and can be driven in a slower, safer and more controlled manner; Operates like a conventional open differential when unlocked; Easy installation and maintenance; With ARB's 24-month limited warranty.
