King Engine Bearings Chrysler 426CI / 440CI V8 OHV Coated Performance Main Bearing Set

These King Engine Bearings main bearing set feature a pmax black coating, a specialized racing surface treatment designed to reduce friction and improve durability under demanding conditions. They are built for Chrysler 426 cubic inch and 440 cubic inch V8 overhead valve engines, commonly found in a wide range of Mopar vehicles from the mid-60s through the mid-70s. If you're rebuilding the bottom end of a classic Chrysler, Dodge, or Plymouth with one of these big V8s, a solid set of main bearings is crucial for proper crankshaft support and oil pressure.

King's pmax black coating is a notable feature for performance applications. It's a tough, low-friction layer that helps protect the bearing surface from wear, especially during the critical break-in period and under high-load situations. This coating, combined with the well-built construction you expect from King, makes this set a strong option for engines that see regular use or are built for more spirited driving. They are designed to fit right into the factory main bearing bores, making installation straightforward for someone familiar with engine assembly.

When assembling your engine, ensure the crankshaft journals are clean and within factory specifications. These bearings are intended for use with the specific 426 and 440 cubic inch V8 engines listed in the fitment. Always refer to your vehicle's service manual for detailed assembly procedures and torque specifications.
