Fuso Canter Positive Front Diff E-Locker - Kit

Take complete control of your front axle traction with the Harrop ELocker for the Mitsubishi Fuso Canter. This premium selectable front differential locker delivers maximum traction exactly when you need it, while retaining the smooth handling and steering characteristics of a standard open differential during everyday driving.

During normal driving, the front differential operates exactly as the factory intended, allowing the left and right front wheels to rotate at different speeds for predictable handling and reduced tyre wear. When additional traction is required, simply press the supplied dash-mounted switch to engage the locker. The differential instantly locks both front axles together, delivering equal drive to each front wheel for maximum available traction in difficult terrain.

Unlike air-operated differential lockers, the Harrop ELocker uses a proven electromagnetic locking mechanism. There are no air compressors, air lines or pneumatic fittings to install or maintain, making it a simple, reliable and low-maintenance solution for serious off-road touring, commercial and expedition vehicles.

How the ELocker Works

Under normal driving conditions, the Harrop ELocker functions exactly like a conventional open differential, allowing the front wheels to rotate independently during cornering for smooth steering and normal road manners.

When additional traction is required, simply press the dash-mounted switch to activate the electromagnetic locking mechanism. The front differential immediately becomes fully locked, ensuring both front wheels receive equal drive regardless of which wheel has traction.

Once the obstacle has been negotiated, switch the locker off and the differential instantly returns to normal open operation.
