Scoop Tray Mount Spacer 4500

The Scoop Tray Mount Spacer 4500 by ALLSTAR PERFORMANCE is a precision aluminum spacer engineered to properly position intake scoop assemblies on Dominator carburetors. Machined from lightweight aluminum and finished in black anodize for corrosion resistance, this 3.5-inch spacer features 5/16-18 threaded inserts that allow secure mounting without compromising the critical airflow path to the carburetor inlet. The spacer maintains exact height and alignment, preventing binding and ensuring the scoop tray sits at the optimal angle for maximum ram-air effect during acceleration.

Black anodized aluminum construction delivers a balance of lightweight strength and durability, resisting oxidation in engine bay environments while maintaining precise dimensional tolerance. The 5/16-18 thread specification matches OEM Dominator carburetor mounting hardware, eliminating the need for adapter fasteners. At 0.12 lbs, the spacer adds negligible weight while its compact footprint—2.05 inches wide by 4.15 inches long—fits within tight engine compartments common to high-performance builds. The rigid aluminum body prevents deflection under vibration, maintaining alignment throughout the engine's RPM range.

This spacer is essential for builders constructing or restoring fuel-injected and carbureted high-performance engines relying on Dominator carburetor intake systems. Proper scoop tray positioning directly influences volumetric efficiency—misalignment reduces ram-air induction, costing power and throttle response. The ALL 99323 spacer eliminates guesswork during assembly, ensuring consistent baseline geometry across multiple builds. Machinists, engine builders, and restoration specialists working with Dominator carburetors will find this spacer indispensable for achieving repeatable, documented setups and troubleshooting carburetor mounting issues.
