AFR - Airflow Research 6208 - AFR Stud Girdles

These AFR stud girdles are designed to eliminate the rocker stud flexing and associated horsepower loss that come with today's high-lift cams and high-pressure valve springs. They are manufactured from anodized aluminum and include hardened rocker arm adjusting nuts and hardware. Available for small block Chevy and big block Chevy applications, the Airflow Research stud girdles will maintain valvetrain longevity throughout the engine's entire rpm range.
