What is the Tri Armor coating?

The Tri Armor coating is a multi-layer protective layer applied to the bearing surface. It's designed to reduce friction and improve wear resistance, which is beneficial for engine longevity, especially in high-stress applications.

Are these bearings a complete set?

No, these are individual upper main bearing shells only. You will need to purchase the corresponding lower shells separately to form a complete bearing pair for each crankshaft journal.

What does the 'HM-14' designation mean?

The HM-14 designation refers to the specific size and application of this main bearing. It's important to match this designation precisely with your engine's requirements for proper fitment and function.

Product Details

If you're rebuilding the bottom end of your engine, especially for high-performance applications, getting the main bearings right is crucial. These Clevite HM-14 main bearing upper shells are designed to provide a solid foundation for your crankshaft. They are part of a system that helps manage the immense forces generated during combustion and rotation.

What sets these bearings apart is the Tri Armor coating. This is a multi-layer coating that helps reduce friction and wear, which is especially important in demanding engine builds. The coating helps protect the bearing surface from the rigors of operation, contributing to longer bearing life and more consistent oil pressure. These are individual upper shells, meaning you'll need to source the matching lower shells to complete the set for each journal.

When installing main bearings, it's critical to ensure the crankshaft journals are clean and within specification. Always refer to the manufacturer's installation instructions and torque specifications to ensure proper assembly and performance of your engine.
