        • Provides traction to both wheels at all times
        • For off-road use only
        • Heavy duty construction

        USA Standard full spools are one of the best ways to assure traction with both rear tires for any dedicated drag racer, sled puller, or off-roader. These USA Standard spools will provide full traction to both rear tires at all times without the need for them to be engaged or having additional components.

        A USA Standard full spool will work with your existing gears and will simply attach to your ring gear and axle shafts to deliver full and equal power to both sides. Due to the fact that your differential will no longer allow the tires to spin independently with a spool installed, it is not recommended for street use.

        Even though we recommend having your new spool installed by a shop, that doesn't mean you couldn't do it yourself. Differentials and spools can be tricky to install and may require tools that most people don't have lying around their garage. If you have any questions or would like additional information, please give us a call.
