Toyota Hilux N70 Front Harrop E-Locker 3.73 & Down

The Harrop E-Locker Toyota front diff lock gives you traction the moment you ask for it. Because it behaves as a normal open differential until you need grip, everyday driving feels exactly as it always did. Then, when the going gets rough, you flick the in-dash switch and both front wheels drive together.

How the Harrop E-Locker Toyota front lock works

Harrop developed the ELocker alongside Eaton, so the locking mechanism is electromagnetic rather than air-operated. As a result there is no compressor, no airlines and no external module to find room for. Once locked, it captures 100% of the available torque and then sends it equally to both ends of the axle.

Inside, precision-forged gears mesh perfectly, which gives better strength than a standard cut gear. In addition, the 4-pinion design spreads the load evenly, while the centre itself is rebuildable rather than throwaway. Installation is drop-in, so a competent workshop will fit it without modifying your housing.

Check your ratio before ordering

However, the ratio matters. This Harrop E-Locker Toyota unit suits 3.73 and numerically lower. If you are running 3.91 or higher, such as 4.10, 4.30 or 4.55, then you need the 3.91 & Up version instead. Not sure which you have? Get in touch and we will work it out with you.

Finally, we can supply and fit here in Christchurch, so ask us for a fitted price if you would rather not tackle it yourself. Otherwise the Harrop installation guide walks through the process step by step.
