What is Lunchbox Locker?

Lunchbox locker is a type of differential found in off-road vehicles. They are used to help get the vehicle through difficult terrains by locking the front and rear axles together.

The name “Lunchbox” is originated from the idea of packing the lunch in a reusable “lunchbox”.

Air lockers are the most common type of lunchbox locker. When activated, they are powered by compressed air, which locks the front and rear axles together.

Electric lockers are also a popular choice for off-road vehicles. When activated, they are powered by electricity, which locks the front and rear axles together.

Cable lockers are the cheapest type of lunchbox locker. They work by locking the front and rear axles together with a cable.

So, how does a lunchbox locker work? Essentially, it locks the front and rear axles together, which allows the vehicle to power through difficult terrain more easily. But, it needs to remain open in normal driving conditions to allow the differential to work properly.

The main advantage of a lunchbox locker is improving the vehicle's traction in difficult terrain. This makes it easier to get up hills and through rough terrain.

The main disadvantage of a lunchbox locker is making the vehicle harder to steer. This is because the locked axles will resist any change in direction, making the vehicle difficult to turn.
