The ARB Air Locker for the GM 14-Bolt 10.5" axle instantly locks both axle shafts together, ensuring maximum power delivery to both wheels. When activated, its pneumatically operated locking system prevents the internal differential gears from rotating independently, tying both wheels directly to the ring gear for unmatched traction.
