The Spartan™ locker is a mechanical locking unit which installs into a standard carrier, replacing the open spider gears. The design of the Spartan™ locker makes it easier and quicker to install than other drop-in locker designs. Spartan lockers use high-Nickel 9310 Chrome-Moly drivers and couplers for added strength. These units provide affordable traction and easy installation. Current applications include D30, D44, D60, Toyota 8” 4 cylinder and Suzuki Samurai, with more applications on the way.
