Overview
The XJX Parts Air Locker is a premium traction aid, keeping your vehicle moving confidently in all conditions. With the flick of a switch, it locks both wheels on an axle together, delivering maximum grip. Its robust design allows activation at any speed, giving you control over the toughest terrains safely and efficiently.
At the heart of the Air Locker is a pneumatic locking system inside the differential. When engaged, it prevents the axle shafts from turning independently, ensuring maximum traction. When disengaged, it operates like a conventional open differential, allowing smooth on-road driving while reducing drivetrain stress.
