About this product
The Kibblewhite C630 Valve Guide offers superior performance and durability for your engine. Precision-engineered and manufactured in the USA, this valve guide is designed to withstand the rigors of high-performance applications, ensuring optimal valve train function and longevity.
Description
Crafted from copper-based C63000 nickel-aluminum bronze, this valve guide provides exceptional wear resistance due to its 5% nickel content. The high copper content (approximately 80%) ensures outstanding heat conductivity, effectively dissipating heat away from critical valve train components. The profile is meticulously designed to minimize airflow disruption while maintaining crucial cross-sectional thickness in high-temperature zones. This combination promotes both high performance and endurance, making it an ideal choice for demanding engine builds. Upgrade to Kibblewhite valve guides and experience the difference in reliability and performance. Compatible for both intake and exhaust applications.
