SuperATV s heavy duty carrier bearing is designed to go mile after mile, giving you a long-lasting and smooth ride. Greaseable and Fully Sealed Unlike the factory bearing, SuperATV’s bearing is greaseable and fully sealed, reducing friction. Self-Aligning Bearing Superior to standard bearings found in others, the SuperATV self-aligning bearing reduces side load on your carrier bearing from the prop-shaft – a must have if you want to keep vibrations to a minimum and the life of your bearing long.
