High Lifters Detroit Gearless Locker for ATV's - doesn't need teeth to get a good bite and steers easier than spool type lockers.

The world famous Detroit Locker - a fully automatic, 100% locking differential that is both durable and speed sensitive to permit differential action in turns. Using no switches, cables, air or external control, the Detroit Gearless Locker is designed for the Harsh environments of mud, water, rocks and other demanding trail hazards. Instead of gears, it is based on a unique high strength, steel disc assembly which allows one wheel to spin faster in a turn but not stop spinning. While driving straight, the differential is locked providing full power to each front wheel. When cornering, the differential allows the outside wheel to travel faster at ground speed.
There is never a condition where one wheel spins and the other is stopped.
