Clevite Main Bearing Set

If you're rebuilding the bottom end of an engine that sees a lot of action, especially in the medium to high RPM range, a solid set of main bearings is crucial. This H-Series set from Clevite is designed for just that. They've got a hardened steel back and a thin overlay, which helps them seat well, especially when you're working with crankshafts that have oversize fillets. These bearings are made without flash plating, a detail that helps ensure they properly seat against the crankshaft. This is important for consistent oil flow and reducing friction, which is key when you're pushing an engine harder.

Clevite's H-Series bearings are a popular choice for performance builds because they're built to handle the demands of higher engine speeds. The medium eccentricity and high crush features are part of what allows them to maintain good oil film thickness and grip, even under stress. This set fits a wide range of vehicles, including popular models like the Mazda Miata, Ford Escort, and Mazda Protege, making them a versatile option for many rebuild projects.
