Detroit Locker - GM 12 Bolt 8 7/8 in. - 30 Spline

The Detroit Locker is a 100%-automatic locking differential that provides ultimate traction for mild to extreme vehicle applications. Its unique, bullet-proof design is engineered to keep both wheels in drive mode - even is one wheel is lifted off the ground.


Operation
During straight-line driving, the Detroit Locker captures 100% of available torque and sends it equally to both wheels. In turns and maneuvers, the internal components unlock to allow one wheel to spin faster or slower as necessary (free wheel). When the vehicle returns to a straight-line driving path, the components re-engage and provide power to both wheel ends.


Performance
Each application is highly engineered, tested and validated for a variety of uses including racing, towing, off-road, rock crawling and street/strip. Choose the Detroit Locker to get the strongest, most durable performance differential available today.
