What does the 0.25 oversized sizing mean for my engine rebuild?

The 0.25mm oversized sizing indicates these bearings are meant for a crankshaft that has had its main journals machined down by 0.25mm. This ensures the correct oil clearance and fit when the journals are no longer at their original factory diameter.

What is the benefit of the PMaxBlack overlay and Radialock feature?

The PMaxBlack overlay provides a superior load capacity, allowing the bearings to withstand higher pressures within the engine. Radialock technology helps maintain the correct crush height during installation, ensuring the bearing stays securely seated and maintains proper oil clearance.

Are these bearings suitable for a performance engine build?

Yes, these bearings are designed with performance in mind, featuring a tri-metal copper-based material, enhanced load capacity with PMaxBlack, and features to ensure proper installation and oil clearance, making them a strong choice for performance applications.

About this part

Product Details

Starting with a tri-metal copper-based material, these main bearings from King Engine Bearings are built for the demanding needs of your Toyota 4AGE or 4AGZE engine. They are specifically sized at 0.25mm oversized, which is crucial when rebuilding or refreshing an engine where the crankshaft journals may have been machined down. This sizing ensures a proper fit and oil clearance for optimal performance.

King has engineered these bearings with their PMaxBlack overlay, which offers a superior load capacity compared to standard materials. This means they can handle more stress and pressure within the engine. Additionally, the Radialock feature helps maintain optimal crush height during installation, ensuring the bearing stays securely in place and maintains the correct oil clearance. These features combine to make a well-built bearing set designed to keep your engine running smoothly.

This set is a direct fit for many Toyota models, including the Corolla, Celica, MR2, and Tercel, as well as the Geo Prizm. If you're rebuilding the bottom end of your 4AGE or 4AGZE engine, these bearings are a solid option to consider for reliability and performance.
