What is the STDX size designation?

The STDX designation refers to a specific size for the main bearings. This size is often used when an engine has been line-bored or requires a specific clearance for optimal performance.

What is the benefit of the Radialock feature?

Radialock is a feature designed to help maintain the correct crush height of the bearing. This ensures the bearing stays securely in place within the engine block during operation, contributing to its longevity and performance.

Are these bearings suitable for a stock engine rebuild?

While these are performance bearings, they can be used in a stock rebuild if you are looking for an upgrade in durability and load capacity. They are particularly well-suited for engines that may see harder use or have had modifications.
