The "V" series were originally manufactured by the Vandervell company in England, Clevite bought Vandervell and is now distributing their bearings under the Clevite name as the "V" series. We feel the "V" series are a great choice for performance bearings. "V" series have found their way into nearly every form of motorsports with virtually no problems. These bearings are still a tri metal bearing, however they use a lead indium overlay instead of the babitt in the above bearings. Lead Indium has amazing properties. It has a super low surface friction coefficient or lubricity, meaning wear at startup before the engine can develop oil pressure is greatly reduced. It can withstand and operate at higher temperatures for longer periods of time. It will resist flaking and peeling under extreme loads better than any other bearing. It has the highest resistance to corrosion of any bearing material, and it does all this while still having unsurpassed properties of embeddability, conformability and fatigue strength. And the best part is just because these perform so exceptionally in a racing environment, there is no reason they can't be used with equal success in a street car or in milder performance engines as well.
