2" Phenolic Square Bore 4BBL Carburetor Spacer

This 2" phenolic square bore 4bbl carburetor spacer is built for carburetor spacing, intake plenum tuning, and carburetor mounting height adjustment on compatible carbureted intake manifolds. The spacer design can help improve airflow transition and simplify carburetor linkage or clearance adjustments depending on the application.

Use it when additional carburetor height, plenum volume changes, or linkage clearance are required. Confirm carburetor flange style, spacer thickness, gasket alignment, hood clearance, and stud length before installation.

Holley 4150/4160-style square bore 4-barrel carburetors and square bore intake manifolds using the matching 4BBL bolt pattern
