King Chrysler 426Ci/ 440Ci V8 OHV- 6 Lower Flanges (Top Fuel) (Size 1.0) Main Bearing Set

These King Engine Bearings main bearings are built with 6 lower flanges, a design choice often seen in high-performance applications like Top Fuel drag racing. They are specifically sized at 1.0 undersize, meaning they are intended for crankshafts that have been machined down by 0.010 inches to correct wear or achieve specific clearances. This set is designed for Chrysler 426 cubic inch and 440 cubic inch V8 overhead valve engines.

King Engine Bearings uses a tri-metal material construction for these bearings, which offers a good balance of strength and conformability. This helps them handle the significant loads and heat generated in powerful V8 engines. The 6 lower flange design helps to locate the crankshaft precisely, preventing excessive movement under stress. This is a well-built set intended for serious engine builds where precise tolerances and durability are critical.

When rebuilding your engine, ensuring you have the correct bearing size is crucial for proper oil clearance and long-term performance. These bearings are a solid option for those working on a performance-oriented Chrysler V8 build.
