1in Super Sucker Carb. Spacer - 4500 w/Clvrleaf

The HIGH VELOCITY HEADS 1-inch Super Sucker Carburetor Spacer with Cloverleaf manifold is a precision aluminum intake manifold spacer engineered to optimize fuel-air mixture distribution and charge cooling in high-performance carbureted engines. The 1-inch thickness increases the volume between the carburetor and intake manifold, reducing charge temperature and promoting more consistent atomization across all cylinders—a critical factor in building reliable power on both street and competition builds.

Machined from aircraft-grade aluminum in its natural finish, this spacer features a Dominator flange pattern for universal compatibility with Dominator-style four-hole carburetors and accepts Cloverleaf manifold mounting. The 4500 designation indicates suitability for large-displacement applications demanding robust flow characteristics. At 2.09 lbs with compact 6.6 x 2.2 x 8.45-inch dimensions, it integrates cleanly into engine bays without requiring extensive modification. The one-piece construction eliminates gasket stack variability and maintains precise throttle response by minimizing carburetor-to-manifold distance tolerances.

This carburetor spacer serves engine builders and tuners working on big-block and stroker engines where charge density and mixture distribution directly impact horsepower, throttle sensitivity, and idle quality. The spacer-style design is particularly effective in applications where stock manifold architecture creates uneven fuel distribution to end cylinders. Part number SS4500-1CAL represents HIGH VELOCITY HEADS' premium offering for builders demanding concentricity, dimensional accuracy, and proven thermal management in carbureted performance engines.
