COMP Cams 4018 COMP Cams Stud Girdles Air Conditioning Hoses and Lines and uneven tire wear causedThe COMP Cams 4018 COMP Cams Stud Girdles are precision machined rocker arm stud girdles designed to eliminate valvetrain flex at high RPM. As valve spring pressures increase and cam profiles become more aggressive, the rocker arm studs can flex under load, introducing valvetrain instability. Stud girdles tie the rocker studs together, creating a rigid structure that maintains rocker arm geometry. CNC machined from 6061 T6 billet aluminum, these
