The Harrop E-Locker is an Australian-made electromagnetic differential locker, engineered as a high-performance upgrade for the front axle of Nissan Navara D23 NP300 models. Designed specifically for differentials with gear ratios of 3.69 and higher, this unit replaces the standard open differential to provide maximum, driver-controlled traction on demand. A standard differential sends power to the wheel with the least grip, leaving you stuck in challenging off-road conditions. The Harrop E-Locker solves this by mechanically locking both front wheels together, forcing them to turn at the same speed and ensuring drive is always sent to the wheel with traction. This locker is compatible with genuine Nissan gearsets 38100-EA48B and 38100-EA58B for reference.

We also have the front diff lock for the 3.54 and lower ratio diff, available separately in our online store. 99-ELKR13120
