King Engine Bearings Chrysler 426Ci/ 440Ci V8 OHV (Top Fuel) (Size 1.0) Main Bearing Set

If you're building a high-performance Chrysler 426 or 440 cubic inch V8 engine, especially for Top Fuel applications, the main bearings are critical for keeping the crankshaft spinning smoothly under extreme stress. These main bearings from King Engine Bearings are specifically made to handle the intense loads and high RPMs these engines produce.

King uses a unique tri-metal material construction that offers improved strength and durability compared to standard bearings. This tri-metal design has a steel backing for solid support, a copper-lead alloy in the middle for heat dissipation and embeddability, and a lead-tin-bronze overlay for reduced friction and wear. This well-built combination helps protect your crankshaft and ensures consistent oil clearance even when the engine is pushed hard. The 1.0 size indicates these are 0.010 inch undersize bearings, meant for crankshafts that have been machined down to match.

When rebuilding a performance engine like this, ensuring proper oil pressure and clearance is key. These bearings are designed to work with the specific demands of these powerful Mopar V8s, providing a solid foundation for your build.
