STUD GIRDLES Moroso Stud Girdles provide high-RPM valvetrain stability for stud-mounted rockers—an absolute must with today’s high lift cams and high pressure valve springs! They’re designed to eliminate rocker stud flexing and the power loss that goes along with it. In fact, dyno tests have shown a 7 to 22 horsepower gain.
SINGLE BAR STUD GIRDLES Moroso Single Bar Stud Girdles feature a sturdy aluminum bar and special heat treated U-bolts to reinforce the rocker stud and provide a positive way to lock the valve lash adjusting nuts. Includes all adjusting nuts and hardware.
DOUBLE BAR STUD GIRDLES Moroso Double Bar Stud Girdles provide even more holding power and reinforcement for applications using extremely high-pressure valve springs.When used with Moroso Hex Head Adjusting Nuts, valve adjustments on Small and Big Block Chevy versions can be made with a single 9/16” wrench and requires loosening only one bolt to adjust one pair of rocker arms.
