Harrop Front Diff Lock E-Locker 3.54 and Down Ratio - Nissan Navara D23 NP300

Harrop Front Diff Lock E-Locker 3.54 and Down Ratio - Nissan Navara D23 NP300

This Harrop E-Locker is fitted inside the front differential housing of your vehicle, replacing the standard "open" differential gears. It is an electronically controlled, selectable locking differential designed to provide maximum traction when you need it most.

An E-Locker is essential for any serious off-road enthusiast. A standard differential allows wheels on the same axle to spin at different speeds. While this is necessary for turning on high-traction surfaces, it becomes a major weakness off-road. If one wheel loses grip (e.g., gets stuck in mud, sand, or lifts into the air), all the engine's power is sent to that spinning wheel, and you lose all forward momentum. By engaging the Harrop E-Locker, you lock the front axle, forcing both wheels to turn at the same speed and ensuring power is always sent to the wheel with traction.

We also have the front diff lock for the 3.69 and higher ratio diff, available separately in our online store. 99-ELKR13684
