With over 70 years of race bearing manufacturing, Mahle Motorsport, formerly known as Vandervell, manufactures the highest quality race bearings available. They have been proven time and time again by F1 race teams, and many other race engine builders. With many special features, these bearings have great wear characteristics added durability. Mahle uses a proprietary tri-metal blend to provide a stiffer bearing under high load use, which is necessary for race engines. Each bearing is designed with state-of-the-art software for the ideal oil film thickness, which adds reliability and greatly reduces the chance of spinning a bearing.
