Made in the USA! The Spartan Locker is a mechanical locker that installs into your stock carrier. This compact and simple design rivals much more expensive lockers. The Spartan Locker features a revolutionary spring-and-pin design that makes this drop-in locker stronger than the Lock Right locker. It features oversized pins (larger than the Lock Right) while the couplers and drivers are made from 9310 chromoly steel to compensate in strength.

These units provide affordable traction without the need of a professional installation. Each Spartan Locker carries a one year warranty against defect and is recommended for lighter vehicles with 35″ or smaller tires.
