Asked by Andrew from Indianapolis, IN on

Andrew, the Detroit Locker AMC Model 20 3.07 Up Automatic Locker will not work on your Patriot. At this time, there is nothing that will work for you.

The Eaton Corporation has enjoyed over a century of innovation and is in the business of powering Jeeps with a top-rate lineup of lockers, open differentials and limited slips. Traction performance is critical while jeeping and we carry Eaton components for upgrading vehicle traction. Compatible with different axle splines and various gears, these parts are often rebuildable and are top performers on and off-road. Eaton's rich tradition of engineering innovative, dependable products extends to off-road parts and accessories for 4x4s and they have evolved to become the industry standard in differentials, lockers and limited slips.
