As more and more OE manufacturers shift to aluminum bearings in OE engines, Clevite has introduced a new line of 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, which includes 60% more silicon than the leading competitor's bi-metal material for better conditioning of journal surfaces. These BiMetal bearings also offer greater wear resistance than the leading competitor's bi-metal material, as well as greater seizure resistance. 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.
