Why we make them Your factory Maverick Sport carrier bearing is notorious for premature wear, leaving you with an undesirable vibration that will lead to other drive train parts failures down the road. 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. Two piece design Snappy install? Yes. The unique, two-piece design makes install and maintenance a breeze. Rather than pressing on a single bearing, SuperATV's two piece is easily positioned and then secured in minutes. SuperATV™s Maverick Sport carrier bearings are made 100% in the USA and are fully machined using state of the art equipment. Billet or Cast? We offer our bearing carrier as a 6061 billet aluminum material or an A380 cast aluminum material to meet anyone™s needs and budget. 6061 billet aluminum is stronger than cast aluminum. It is intended for racers and riders who ride hard and frequently push their machine to its breaking point. A3280 cast aluminum is a tough material that™s many times stronger than stock. It™s perfect for the average rider who wants to upgrade to a bearing carrier that™s longer lasting and more reliable than OEM.
