Clevite Cat 4 3204 Main Bearing Set

If you're rebuilding the bottom end of your engine, a solid set of main bearings is crucial for proper crankshaft support and oil flow. This Clevite MS2020P10 main bearing set is designed to be a direct replacement for your stock bearings, ensuring your crankshaft spins smoothly and stays properly aligned within the engine block.

Clevite is known for making well-built engine components, and this bearing set is no exception. They use a layered construction with a steel backing for strength, a bronze-iron alloy intermediate layer, and a bearing surface designed for good oil retention. This combination helps manage friction and heat, which is essential for the longevity of your engine, especially during the critical break-in period after a rebuild.

This set is specifically for the Cat 4 size, meaning it's 0.010 inches undersize. Make sure this is the correct size for your crankshaft journals before ordering. Proper installation, including ensuring the crankshaft journals are clean and within spec, is key to getting the best performance and life out of these bearings.
