LOCKED & LOADED
A KEY product in Harrop Engineering’s 4x4 range is its Elocker. The Aussie company saw the potential of the Eaton Elocker from the USA and redeveloped it using a stronger four-pinion-design differential. Harrop also casts and machines the carriers in-house to suit popular 4x4 vehicles.
The simplicity of the Harrop-eaton Elocker centres on its electromagnetic actuation, which means there’s just one wire going to the differential. That means no air compressors or lines are needed, as with many other locking differentials. A single wire comes back from a relay mounted in the engine bay, with its switch located in the cabin. Once powered, the electro-magnet locks the two sides of the differential together to send equal drive to both wheels. Simple, selectable traction!
While the rear diff lock that’s factory-fitted to the Ranger is also electronically actuated, its manufacturer isn’t known. However, even if it’s a Us-sourced Eaton Elocker, it won’t be as strong as the Australianmade Harrop derivative.
Harrop Elockers are available for most popular 4x4 models.
