As more and more OE manufacturers shift to aluminum bearings in OE engines, Clevite has introduced a line of A-Series engine bearings designed to be the highest quality replacement bearings in the industry. Clevite BiMetal™ engine bearings carry on the tradition and reputation that Clevite has built throughout the course of time.Clevite BiMetal engine bearings feature a 100% lead free aluminum-silicon bi-metal material; this includes 60% more silicon than leading competitor's bi-metal material for better conditioning of journal surfaces. These BiMetal bearings also offer greater wear resistance than leading competitor's bi-metal material, as well as greater seizure resistance than the leading competitor. Clevite BiMetal bearings feature 100% bored ID's for precision and surface characteristics and where appropriate - straight shell main bearings utilizing an "umbrella" groove that allows for superior oil control and improved pressure. Widely used at the OEM level in the past 15 years, bi-metal bearings are a very good choice for stock replacement parts on engines that have bi-metal bearings from the factory. Show more
