Product Details

When you're tackling challenging terrain or need extra grip off-road in your Porsche Cayenne, having a differential that can lock on command makes a huge difference. The Eaton ELocker is an electronic, selectable differential that lets you switch from an open differential for normal driving to a 100-percent locked differential instantly. This means you get maximum traction exactly when you need it, and can disengage it just as easily for smooth road manners.

This ELocker is built for strength, featuring a 4-pinion net-forged gear design that's made to handle demanding use. The electromagnetic locking mechanism is known for its reliability, making it a popular choice for drivers who need their equipment to perform consistently. It works effectively in both forward and reverse, giving you confidence no matter the situation. You'll also find that it fits right into the Porsche ZF IFS axle, specifically model 955-349-010, and is designed for 37-spline axles with compatible gear ratios like 4.56, 4.10, 3.90, and 3.73.

Installation includes a dash-mounted push-button switch and a wiring harness from Eaton, so you have the essential components to control the locker. This setup allows you to go from open to locked and back again with a simple flip of the switch, giving you the best of both worlds: efficient open-diff cruising on the street and serious locked-diff traction when you leave the pavement behind.
