CNC'd to exact specifications, PRW 6061-T6 Billet Aluminum Stud Girdles eliminate valvetrain instability by reducing rocker stud flex and retaining critical valve lash adjustments for more accurate valve lift and timing. Girdles are relieved at the factory to accommodate crankcase evacuation components.
