Clevite Main Bearing Set

Clevite is a well-known name in engine components, particularly for their bearings that are often found in performance and racing applications. This Main Bearing Set, part number MS1625P20, is built with that same focus on durability and performance. Main bearings are critical for the health of your engine; they sit between the crankshaft and the engine block, supporting the crankshaft and allowing it to spin smoothly while handling immense forces.

This particular set is designed to be 0.020 inches undersize, which is important to note if you are re-machining your crankshaft. The construction uses a tri-metal material, a common and effective choice for high-performance bearings that offers a good balance of strength, conformability, and embeddability. This means the bearing can adapt to minor imperfections in the crankshaft surface while still providing a strong, wear-resistant layer. The goal here is to ensure consistent oil film support and reduce friction, which is key to engine longevity and power output, especially under demanding conditions.

When rebuilding or refreshing an engine, especially one that will see harder use, choosing the right bearings is crucial. This Clevite set is a solid option for those looking for a well-built component that can handle the stresses of performance driving. Always ensure your crankshaft journals are properly machined to the correct undersize specification before installing these bearings, and refer to the manufacturer's installation instructions for detailed guidance on assembly and lubrication.
