Eaton sent us a trail-proven Detroit Locker to use for this project. We picked this differential because they rarely, if ever, fail. The design utilizes robust internal parts to ensure that 100-percent traction is delivered to both drive wheels whenever torque is applied. The Detroit Locker automatically allows wheelspeed differentiation when needed. This enables the inside wheel to track around a corner at a slower speed than the wheel on the outside of the corner.
