The Spartan Locker is a mechanical locking device that replaces the spiders in a standard case. It has a spring and pin design which facilitates easy installation. The Spartan Locker has couplers and drivers constructed using 9310 steel, which provides additional strength. The purpose of the Spartan Locker is to offer reliable traction over rough terrains. It does not use thrust washers and most of them have a cross-pin shaft.
This automatic locker replaces the stock side and pinion gears and utilizes the factory open differential case. A new and stronger center pin fits into oval slots between the two inner drivers. Under load, the center pin forces the inner drivers outward to engage the outer axle couplers on each side of the case. This provides locked power to both drive wheels, providing greater traction. While turning, one driver is unloaded and the teeth can ratchet across each other creating differential action to reduce tire wear and make it easy to turn the vehicle. This is one of the most economical lockers on the market today.
