Video: How Upgraded Bearings Boost Engine Performance

“Upgrading even the most basic engine parts like engine bearings can give you a great performance advantage,” said Summit Racing tech expert Norm Koval.

In this short tech tip video from Summit Racing and Powerblock TV, you’ll hear Koval explain how specialty coatings which reduce friction, and include certain machined design elements give performance bearings high crush factors and the ability to maintain concentricity under load.

Koval uses Clevite H-Series main bearings — originally developed for NASCAR racing — to demonstrate how high-tech main and rod bearings contribute to boosting engine performance.
