King Engine Bearings Subaru EZ30/EZ30D (Size .025 Oversized) Performance Main Bearing Set

Starting with the PMaxBlack material, these main bearings from King Engine Bearings are built to handle more load than stock. They are specifically sized at .025 inches oversized, meaning they are intended for use with crankshafts that have been machined down by that amount during an engine rebuild. This is a common practice when an engine has seen significant wear or is being rebuilt to higher performance standards.

King has been specializing in engine bearings since 1960, and their focus shows in the details. The PMaxBlack construction uses a tri-metal copper-based material that offers a strong foundation for durability. Combined with their Radialock feature, which helps maintain optimal crush height during installation, these bearings are designed to seat properly and perform reliably. If you're rebuilding the bottom end of your EZ30 or EZ30D Subaru engine, these bearings are a well-built option for improved performance and longevity.
