The JK already had electric lockers and we had become spoiled by their silent and maintenance-free performance. We've used other types of lockers in the past and had very good success. However, the overwhelming benefits of the Eaton E-Locker were impossible to pass up for this project. The E-Locker comes with a complete wiring harness and illuminated rocker switches. Strength is not a concern. The dependability of the Eaton E-Locker is so good that AM General and the U.S. military used them in the H1 Hummer with tremendous success.
