BARTOO Aluminum Carburetor Spacer 1" for 5-1/8" Opening — Lightweight Corrosion-Resistant Fit

BARTOO's 1-inch aluminum air cleaner spacer provides a durable, corrosion-resistant gap between a carburetor and air cleaner for engines with a 5-1/8-inch carburetor opening.

Designed as a direct-replacement spacer, this part uses precision-formed aluminum to maintain a tight seal and reliable fit on popular carburetors such as Holley, Edelbrock, Rochester, Demon, Carter and similar units with a 5 1/8-inch opening. It installs quickly, resists warping, and preserves proper clearance between the carb and the air cleaner for improved serviceability and component protection under everyday driving and mild performance use.

How does this spacer improve clearance and maintenance?

The 1-inch thickness creates extra room between the carburetor and the air cleaner assembly so tall aftermarket filters or linkage will not bind. That gap also makes it easier to access choke rods, throttle linkages and install gaskets without removing the air cleaner.

• One-inch lift for improved clearance under tall filters and velocity stacks
• Allows easier access to choke and throttle linkages
• Enables use of thicker gaskets and seals without interference

Will this spacer fit my carburetor and intake combination?

This spacer is sized specifically for carburetors with a 5-1/8-inch mounting opening, a common diameter on many Holley, Edelbrock, Rochester, Demon and Carter carbs. It is designed to match standard bolt patterns and mating surfaces for straightforward installation on compatible risers and intakes.

• Compatible with 5 1/8-inch carburetor openings
• Works with Holley, Edelbrock, Rochester, Demon, Carter type carbs
• Matches standard bolt pattern and mounting surface dimensions for direct replacement

What materials and build quality can I expect?

The spacer is machined from high-quality aluminum for light weight and corrosion resistance. Manufactured to standard tolerances, it resists distortion from heat and vibration while providing a reliable sealing surface when used with appropriate gaskets and hardware.

• High-grade aluminum construction for durability and low weight
• Precision-formed for consistent sealing surfaces and bolt alignment
• Manufactured to standard fitment tolerances for reliable replacement use

How simple is the installation process?

Installation is straightforward and typically needs only common hand tools. The spacer can act as a direct replacement—remove the air cleaner and carburetor, place the spacer with a gasket, then reinstall components, ensuring proper torque and alignment.

• Simple drop-in design for quick replacement
• Works with standard gaskets and hardware—no special tools required
• Recommended to torque bolts evenly to prevent leaks or misalignment

Who is this for: This aluminum air cleaner spacer is aimed at classic car restorers, street-rod builders, and mechanics who need a reliable, lightweight spacer for carburetors with a 5-1/8-inch opening. It’s a practical choice when extra clearance, easier linkage access, or a direct-fit replacement is required without altering carburetor geometry or intake alignment.
