How Detroit Lockers Work:

The Detroit Locker is a 100% Automatic, Wheel Speed Sensitive locking differential. Engineered to keep both wheels in a constant drive mode whenever torque is applied, the Detroit Locker has the ability to automatically allow wheel speed differentiation. It’s as simple as this: 100% locked and functioning like a spool when you’re on the gas, and able to unlock when coasting and cornering.

With a reputation for delivering traction in mud, snow, rocks and on the track, the Detroit Locker is one of the strongest and simplest traction devices available on the market today.

Do the job once and do it right, with our help. Lockers in stock for Jeep, Ford, GM, Chrysler, Hummer & Isuzu vehicles.


We stock the entire line of Eaton Performance Differentials, including the Detroit Locker®, Eaton ELocker®, Detroit Truetrac® and Eaton Posi™.
