1/2inPLASTIC PHEN.OPEN S PACER

The TRANS-DAPT 1/2 Inch Plastic Phenolic Open Spacer (SKU TRA2180) is a precision carburetor spacer engineered to optimize intake manifold-to-carburetor positioning on small-block and mid-sized V8 engines. This half-inch thick open design accommodates direct airflow while maintaining proper carburetor height and fuel delivery geometry. The plastic phenolic construction provides thermal insulation between the hot intake manifold and carburetor, reducing fuel evaporation and vapor lock issues during sustained driving or high-ambient-temperature operation.

Carburetor spacers play a critical role in fuel system tuning by creating distance between the manifold and carb, allowing for better air distribution through the intake runners. The 0.5-inch thickness in this TRANS-DAPT spacer is a popular OEM specification for street and mild-performance applications where you need thermal isolation without excessive height. Phenolic material resists heat degradation and won't absorb fuel vapors like composite alternatives. This spacer ships complete with gaskets and mounting hardware—no additional seals or fasteners required. The open design means unobstructed flow passage, critical for engines running carburetors in stock or slightly modified configurations.

This spacer is ideal for carburetor restoration, engine rebuilds, and small-block swaps where factory spacing dimensions must be restored or adjusted. Mechanics and engine builders working on Chevrolet, Pontiac, Buick, and Oldsmobile applications with 2-barrel or 4-barrel carburetors will find the TRANS-DAPT 2180 spacer a reliable, cost-effective solution. It's particularly useful when replacing worn or damaged original spacers that have degraded from fuel contamination or thermal cycling. The black phenolic finish resists staining and maintains appearance in engine bays.
