What does the STDX size mean for these bearings?

The STDX designation indicates that these bearings are 0.040 inches undersize. This is a common size used when rebuilding or modifying an engine where the crankshaft journals have been machined down to ensure proper clearance.

What is the benefit of PMaxBlack overlay and Radialock technology?

PMaxBlack overlay is designed to provide superior load capacity, helping the bearings withstand higher pressures without failing. Radialock technology helps maintain the correct amount of 'crush' when the bearings are installed, which is crucial for proper seating and oil retention.

Are these bearings suitable for a performance build?

Yes, the tri-metal copper-based material, PMaxBlack overlay, and Radialock technology are all features that contribute to enhanced durability and load handling, making them a solid choice for performance applications.

About this part

Product Details

These King Engine Bearings connecting rod bearings use a tri-metal copper-based material, which is a solid foundation for handling the demands of a BBC engine. They are specifically sized STDX, meaning they are 0.040 inches undersize, which is important for rebuilding or modifying engines where the crankshaft journals have been machined down.

King built these bearings with their PMaxBlack overlay, a feature that helps them handle higher loads without deforming. They also incorporate Radialock technology, which helps maintain the correct amount of crush when installed. This combination of materials and design helps ensure consistent oil clearance and optimal performance for your engine's rotating assembly.

This set is designed to fit a wide range of Chevrolet big-block engines from Gen IV, V, and VI, including popular applications like the Chevrolet Bel Air, Camaro, and Corvette from the mid-60s through the mid-70s, as well as later models like the C1500 and C2500. Make sure to check the full fitment list to confirm compatibility with your specific vehicle.
