The latest technology in carburetor spacers lightened by reducing the profile (or footprint) and pocket milling the 1'' and 2'' varieties. Our design utilizes a wider slot without undercutting the integrity mounting bosses to keep weight at a minimum. The weight reducing slot also offers a cooling effect to the carburetor by the elimination of material thereby reducing the ''Heat Sink Effect''. Clear anodized finish. Gaskets and mounting studs sold separately.
