Today, our limited slip differentials product portfoilio also includes the Eaton Detroit Truetrac helical gear design. Be sure to ask your dealer if your vehicle has an Eaton differential.

Eaton’s EGerodisc™ electronic slip differentials made its commercial debut on the 2005 Jeep® Grand Cherokee, which was named 4x4 of the Year by 4-Wheel & Off-Road magazine.

EGerodisc™ is a hydraulically-operated electronically controlled limited slip differential that is capable of providing variable torque up to full axle lock, helping to maximize traction when needed. The EGerodisc™ can be used as a stand-alone product that provides ultimate traction control, or it can be integrated with ABS or stability control packages to also provide enhanced vehicle dynamics.

The Locker makes towing large boats and campers a breeze. Be sure to ask your dealer if your vehicle has an Eaton differential.
