Speedmaster Phenolic Carburetor Spacer Square Bore

The Speedmaster Phenolic Carburetor Spacer (also called a phenolic / Bakelite carb spacer) fits between a square bore carburetor and the intake manifold. It helps the carburetor-to-manifold transition flow smoothly, which can improve performance. It also insulates the carburetor from engine heat and adds clearance for throttle linkages.

Key Features:

• Phenolic (Bakelite) plastic construction acts as a heat barrier between the intake manifold and the carburetor
• Square bore design for square bore carburetor mounting flanges
• Designed for a smooth flow transition from the carburetor to the intake manifold
• Adds clearance for linkages
• Black finish
• Made in the USA by Speedmaster

Phenolic spacers are lightweight and resist heat transfer better than metal spacers. They suit street and racing carburetor setups, and they are a simple bolt-on upgrade. Select the variant that matches your intake manifold's port configuration.
