King Engine Bearings Chevrolet 396/400/427/502 (Undersize 0.30in) SI-Series Main Bearing Set

If you're rebuilding the bottom end of a big-block Chevrolet engine like the 396, 402, 427, or 502, a solid set of main bearings is crucial for proper crankshaft support and oil flow. This set from King Engine Bearings is designed for those specific applications, offering a 0.030 inch undersize to help you achieve the correct clearances if your crankshaft journals have been machined.

King specializes in bearings, and this SI-Series set is built with a lead-free composite material. This bi-metal aluminum construction is well-suited for medium-load engines, providing reliable performance. The 0.030 inch undersize means these bearings are intended for use with a crankshaft that has been turned down by that amount to correct wear or damage.

This main bearing set fits a wide range of Chevrolet vehicles from the mid-60s through the early 2000s, including models like the C10 Pickup, Camaro, and Corvette. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
