USA Standard Gear Full Spools

USA Standard Gear full spools can handle more torque and provide a more rigid ring gear platform than mechanical lockers—and weigh less, too. These full spools do not have any moving parts and are designed to provide equal torque to each wheel all the time. Since they don't allow for differentiation, they're not recommended for use on the street. Mud boggers find these spools able to stand up to tall tires and provide excellent straight line traction. Many drag racers and mud boggers need tough, reliable, and rigid differentials that offer complete lock-up of the axles. For straight line performance, choose the USA Standard Gear full spools that fit your axle.
