Clevite Case 251 267 284 301 336 Series 4 Cyl 377 401 451 Series 6 Cyl Con Rod Bearing Set

These Clevite connecting rod bearings are built with a tri-metal construction, meaning they have three distinct layers of material. This design helps them handle the high pressures and temperatures found in an engine's rotating assembly. They are designed to be a direct replacement for your stock bearings, making them a popular choice when you're rebuilding an engine or replacing worn-out components.

The tri-metal design is key here. The steel backing provides a strong foundation, while the intermediate layer and the overlay work together to reduce friction and wear. This combination is what allows these bearings to perform reliably under demanding conditions. When you're putting an engine back together, getting the bearings right is crucial for its longevity and performance.
