How Does The Spartan Locker Compare To Other Lockers?

(To skip ahead to the Spartan Locker section of the video, go to minute 21:35 or click here.)

Spartan Lockers are ratchet style lockers (similar to Detroit Lockers) that replace the differential spider gears to provide reliable traction at a low cost while still allowing for wheel speed differentiation when turning on high traction surfaces like pavement. Unlike other "lunchbox" lockers, the Spartan locker's design does not use thrust washers and has a revolutionary spring and pin design that makes them very easy to install without needing to remote the differential carrier from the axle. The couplers and drivers are made from 9310 steel for added strength and everything is covered by a one year warranty.

Spartan Locker Installation

(Installation can also be performed with the differential still mounted in the axle housing.)
