Performance differentials began with the Detroit Locker differential. It is one of the most durable and dependable locking differentials on the market today. It provides 100% torque to both drive wheels so they both pull through the mud or snow. The Detroit Locker does allow for different wheel speeds. Detroit Truetrac is another Eaton branded product that delivers great performance. It is a helical gear style LS differential and has no wearable parts, making it virtually maintenance free. Detroit Truetrac differentials are smooth, tough and quiet.
