Stabilize Valve Train to Increase Horsepower
We engineered JEGS Stud Girdles to work with high-pressure springs, high lift cams, or engines turning high RPMs. They support and strengthen your rocker studs keeping valve train deflection to a minimum which could cause loss of horsepower or even component failure. They also provide fewer valve-lash adjustment sessions. Machined from billet aluminum for maximum strength and anodized in a clear finish. Includes adjusting nuts for use with .600 in. slotted rocker arms.
