4150-4500 Holley Carb Dual Throttle Return Spring Kit 10950

B&B 4150 – 4500 Dominator Dual Throttle Return Spring Kit with Mount PN 10950. Insures prompt return of the throttle lever to avoid any “stuck throttle” situations. Our split bushings allow you to use a 1/4″ fastener in the Holley standard 1/2″ hole found in all Holley and other linkages and lets the rear spring tab “float” without binding up. The front spring bracket mounts on the front carburetor mounting bolt. Dual Throttle Return Springs are required by many racing organizations.
