All Balls Wheel Bearing and Seal Kits contain all of the bearings and seals required to re-fit a wheel. We offer the most extensive line of kits for most street, off-road and ATV applications. Our experience is that wheel bearings typically fail from water and dirt contamination. The All Balls wheel bearing was developed in partnership with KML Bearing and is designed for the difficult operating environment of the Power Sport Industry. Our bearings are a premium EMQ quality, high-speed bearing featuring low drag, double-lip rubber seals which provide superior exclusion of water and dirt and improved grease retention. The All Balls, type TC, Nitrile Elastomer wheel seals are specifically designed to keep out water and dirt. The rubber coated outside diameter creates an optimum seal at the hub. The steel garter spring guarantees constant pressure on the axle shaft over the life of the seal.
