Top 6 Best Automotive Replacement Engine Main Bearings

Designed to be the highest quality replacement aluminium engine bearings available, Clevite Bimetal engine bearings set the standard. Relatively harder aluminium alloy wears well, interacts closely with journal surfaces for strength. Recommended for use with nodular iron crankshafts. Manufactured with 100 bored inside diameters for optimum surface characteristics and consistent precision. Manufactured to meet or exceed OE specifications.

Manufactured from cast copper-lead, increases fatigue strength by approximately 20 compared to powdered metal processes, referred to as sintering, which is used by the competition. Provides a margin of forgiveness for vehicles that don't get maintenance service as often as they should. Additional embed ability makes it a good choice for older engines. Manufactured to meet or exceed OE specifications.

H-Series bearings are narrowed for greater crankshaft fillet clearance. All H-Series bearings are made in Atlantic, Iowa USA. High crush for better seating and retention. Un-plated hardened steel backing for better dimensional accuracy and bore contact.
