The Detroit Locker is normally locked and automatically unlocks as needed in turns, then re-engages to send torque to both rear wheels when traction is required. It is a popular choice for off-road, rock crawling, towing, and street-driven applications where maximum traction is the priority.

Lubrication: Use a quality GL-5 gear oil per the axle manufacturer’s recommendations.
