This simple carb support bolts directly to lower the intake bolt and the center case stud on Harley-Davidson Shovelhead engines. It also allows for fuel line to pass through keeping it off the cylinders. Don't let your carburetor just hang there! This carburetor support bracket Made from Stainless Steel in a tumbled finish. Made in Ohio, USA. Carburetor support brackets should be used when not using a stock air cleaner and backing plate. Most stock setups, including the S&S Super E backing plate, have support for the carburetor integrated into the design. When running a custom air cleaner on a Harley-Davidson, the carburetor support bracket makes sure that the carb is securely mounted so the manifold can't rotate, making the carb sag downward. When running a custom air cleaner (such as a Lowbrow Louvered Air Cleaner or a Gasbox Dog Dish Air Cleaner) on a Harley-Davidson Evolution Big Twin or Sportsters engines or a Twin Cam engine, breather bolts are often needed to complete the installation. The mounting holes are spaced 5-1/4 inches center to center, and the overall bracket length is 6 inches.
