The ARB Air Locker differential for 14-bolt GM 10.5-inch applications features a 30-spline spine shaft and is designed to offer selectable, pneumatic locking across a range of gear ratios. When activated it locks both axle shafts for maximum traction, and it functions as a conventional differential when unlocked for normal driving. Kit contents include the Air Locker, activation switch, solenoid valve, air line and bulkhead fitting; an air compressor is required separately.
