Clevite Oldsmobile 260 307 330 350 403 V8 1964-90 Main Bearing Set

Clevite Main Bearing Set for Oldsmobile 260-403 V8 engines (1964-1990). A well-built replacement for worn engine bearings. These Clevite main bearings are built with a tri-metal construction, featuring a steel-backed overlay that’s bonded to a lead-tin-copper alloy. This design helps them handle the heavy loads and heat generated inside your V8 engine. If you’re rebuilding the bottom end of your Oldsmobile, Buick, Cadillac, or Chevrolet with a 260, 307, 330, 350, or 403 cubic inch V8, these bearings are a solid option to ensure proper crankshaft support. The tri-metal material is known for its ability to conform to the crankshaft journal, which helps maintain consistent oil film thickness. This is crucial for reducing friction and wear, especially in engines that have seen a lot of miles or are being put back into service after a rebuild. Clevite has been making engine bearings for a long time, and this set is designed to fit right into the specified engines, making installation straightforward for a mechanic or a dedicated DIYer. This set is designed for a range of vehicles, including popular models like the Oldsmobile Cutlass Supreme, Chevrolet Caprice, and Buick Electra from the 1970s and 1980s. When you’re putting your engine back together, using well-built bearings like these is key to a long-lasting rebuild.
