King Engine Bearings Ford 330/352/360/390/410/428 Engine (Size 020) Main Bearing Set

King Engine Bearings has been specializing in engine bearings since 1960, aiming to supply the highest quality available. This main bearing set, part number MB559AM020, is built with a lead-free, environmentally safe composite on a bi-metal aluminum material, making it ideal for low to medium-load engines. It's specifically sized 0.020 inches undersize for Ford engines like the 330, 352, 360, 390, 410, and 428.

This set fits a wide range of vehicles, including popular models like the Ford F-100, Ford Fairlane, and even the AC Cobra. The bi-metal aluminum construction offers a good balance for engines that aren't under extreme stress, providing reliable performance. Because these are sized 0.020 inches undersize, they are intended for use when the crankshaft journals have been machined down to match this specification during an engine rebuild.
