Collection: Detroit Locker & NoSpin Assemblies | Traction Solutions

Trucks with conventional differentials often get stuck when one wheel loses traction and begins to spin. The NoSPIN® locker solves this problem by delivering maximum engine power to both drive wheels, regardless of the traction conditions. Additionally, it automatically unlocks to allow for necessary differences in wheel speed when needed.
