MAIN BEARING SET

The Sealed Power 130M Main Bearing Set is a competition series standard size main bearing set for Small Block Ford 351W engines from 1977-1998. It features a 3/4 groove design and is constructed from tri-metal material, engineered for demanding applications and proven in racing conditions. The bearings include a patented contoured-flange design for increased thrust-load capacity and a three-quarter-length oil groove for enhanced lubricity without compromising load capacity. DUROSHIELD® Competition Series Coated Bearings provide protection against dry starts and conditions that interrupt oil supply. Sealed Power's H-14 Super Duty Alloy offers high durability and corrosion resistance, while the H-24 Alloy provides desirable fatigue resistance and strength. B100 babbitt material is used in ultra-high-performance rod and main bearings for blown-fuel and alcohol engines.
