Description

The Clevite P-Series Main Bearings MS-685P is a set of direct replacement main bearings designed for high-revving engines. These bearings feature a tri-metal construction with a steel back, a cast copper lead lining, and an electroplated babbitt overlay for durability and superior surface qualities. The oil grooves on most applications extend fully around both halves for improved oiling.

This set is ideal for rebuilding engines for demanding applications such as heavy-duty, motorsports, or street performance, offering enhanced conformability, embedability, slipperiness, and fatigue resistance compared to original equipment bearings.
