Clevite MS-909H Engine Crankshaft Main Bearing Set

The Clevite MS-909H Engine Crankshaft Main Bearing Set is designed for high-performance applications. Manufactured from cast copper-lead, these bearings increase fatigue strength by approximately 20% compared to traditional powdered metal processes. The H-Series bearings are specifically narrowed for greater crankshaft fillet clearance and are made in Atlantic, Iowa, USA. They feature high crush for better seating and retention, along with un-plated hardened steel backing for improved dimensional accuracy and bore contact. Ideal for crankshafts with oversize fillets and engines operating in medium to high RPM ranges. • Manufactured from cast copper-lead for enhanced fatigue strength • H-Series bearings are narrowed for greater crankshaft fillet clearance • Made in Atlantic, Iowa, USA for quality assurance • High crush design for better seating and retention • Un-plated hardened steel backing for improved dimensional accuracy
