About this part

Product Details

This product is a set of ten main bearings from King Engine Bearings, specifically sized at 0.020 inches undersize for Ford 370, 429, and 460 cubic inch V8 engines. These bearings are designed for medium-load applications and are constructed from a bi-metal aluminum material. They are also lead-free and environmentally safe, making them a responsible choice for engine rebuilds.

King Engine Bearings has been specializing in engine bearings since 1960, focusing on supplying well-built components. This particular set utilizes a lead-free composite and bi-metal aluminum construction, which is ideal for engines that aren't subjected to extreme, constant high-RPM loads. The 0.020 inch undersize specification means these are intended for crankshafts that have been machined down by that amount during a rebuild.

This set fits a wide range of Ford vehicles from the late 1960s through the late 1990s, including models like the Ford F-250, E-350 Econoline, and LTD. Always consult your vehicle's service manual for specific installation procedures and torque specifications when rebuilding your engine.
