Operation

Normally locked, during straight-line driving, the Detroit Locker sends 100% of available torque to both wheels equally. During 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 straight-line driving, the components re-engage and provide power to both wheels.

Performance

The Detroit Locker is highly engineered, tested and validated for a variety of uses including racing, towing, off-road, rock crawling and street/strip. No other performance differential can match its reputation for delivering traction in mud, snow, rocks and on the track.

Lubrication

A quality petroleum GL5 rated (mineral) based oil is recommended. Synthetic oils may also be used if desired per axle manufacturer’s recommendations

Features

Normally locked, with automatic, speed sensitive unlocking as needed

Provides maximum amount of traction to both wheel ends
