In "Locker Lowdown" (Aug. '99) we promised a test of the new Detroit Gearless Locker as soon as we got our hands on one. Shortly after that, 4 Wheel Parts Wholesalers supplied us with a model for a Dana 35C with ABS. At the time it was the only version available, but other units should be available by the time you read this.
We took the Gearless and a '96 Jeep Cherokee to M.I.T. for the install. Rick Dziezyk at M.I.T. led us through the procedure and showed us a couple of tips when putting the unit in a Dana 35C.
With the new locker in place, we started logging miles and jotting down notes. The new locker doesn't make as much noise as its E-Z Locker brother, but it still lets you know it's back there, especially in parking lots. Tires chirp in tight corners, but there is little or no locker-related jerking and banging. In the dirt the Gearless Locker performs much like any other locker. It worked flawlessly and provided good traction over the rough stuff.
