    If you’re only working with one wheel at the track or on the trail, then you’re just spinning your wheels. For the ultimate upgrade in traction, equip your ride with USA Standard Gear Spartan Lockers. These mechanical-locking differential upgrades deliver 100% power to both wheels for amazing grip and performance. Plus, one side automatically disengages during turns for hairpin handling.

    Forget about thrust washers—your Spartan Locker mounts in place using an ingenious spring and pin design for an easier installation. And since it’s custom-designed to replace your stock spiders, you don’t have to sweat modifying your diff for dominate handling.

    Strength is built into all Spartan Lockers. The couplers and drivers are constructed with 9310 steel for lasting durability under even the harshest conditions. USA Standard Gear covers your Spartan Locker with a 1-year warranty.
