What is the pMax Black coating for?

The pMax Black coating is a racing-grade tri-metal material. It's designed to reduce friction and improve oil flow, helping to protect the bearings during high-stress engine operation.

Are these bearings suitable for stock engines?

While these bearings are built for performance, they can be used in stock engines if they are being rebuilt and are equipped with aluminum connecting rods. The STDX size and coating are geared towards enhanced performance and durability.

What does 'predoweled for Alum Rods' mean?

Predoweled means the bearings have a built-in locating feature that helps them stay in place within the connecting rod. This design is specifically optimized for the way aluminum connecting rods function and are assembled.
