BARTOO Aluminum Carburetor Spacer 2" Lift for 5-1/8" Opening — Machined Fit for Holley/Edelbrock

BARTOO's 2-inch aluminum air cleaner spacer raises and spaces a 5-1/8-inch carburetor opening to improve fitment and clearance while preserving reliable sealing.

This machined aluminum spacer is built to sit between the carburetor and air cleaner on engines using a 5-1/8" carburetor opening (common on Holley, Edelbrock, Rochester and similar units). It provides a precise 2" lift to create additional clearance, alter induction path geometry, and accommodate aftermarket air cleaners or odd-frame manifolds. Constructed from high-quality aluminum, the spacer is made for a direct replacement installation and engineered to match OEM dimensions to keep sealing and performance consistent.

How does this spacer affect clearance and fitment?

The 2" height gives you extra space between the carburetor and the air cleaner, solving interference with tall filters, linkage, or hood components. Because it's made to fit a 5-1/8" carburetor opening, it slides into common bolt patterns and aligns ports to avoid modification.

• 2" lift increases vertical clearance for taller air cleaners and breather elements.
• Matches 5-1/8" opening bolt pattern for Holley, Edelbrock, Rochester style carbs.
• Minimizes need for cutting or custom adapters in most installations.

Will installation keep a reliable seal and do I need special gaskets?

This spacer is manufactured to standard dimensional tolerances to maintain a dependable seal when used with proper gaskets. It’s designed for straightforward installation and to accept standard carburetor and air cleaner gaskets; using new gaskets is recommended to ensure leak-free operation.

• Precision-machined surfaces to match carburetor and air cleaner flanges.
• Compatible with standard carb and air cleaner gasket sets (replace gaskets during install).
• Direct-replacement fit reduces risk of vacuum leaks when installed correctly.

Which carburetors and engines does this spacer fit?

Designed for carburetors with a 5-1/8" opening, the spacer is compatible with many popular aftermarket and OEM carbs. Typical fits include Holley, Edelbrock, Rochester and similar models used on small- and big-block V8s, offering common fitment for SBC and BBC applications.

• Fits Holley, Edelbrock, Demon, Carter, Rochester style carbs with 5-1/8" opening.
• Appropriate for SBC and BBC intake/riser applications where 2" lift is desired.
• Works as a riser for Ford and other V8 engines using the same carb flange dimensions.

What are the material and durability expectations?

Made from high-quality aluminum, the spacer offers a balance of light weight and corrosion resistance for long service life. It is produced under standard manufacturing controls to ensure dimensional stability and consistent performance under engine bay conditions.

• High-quality aluminum construction resists rust and keeps weight low.
• Stable performance under heat exposure typical in engine compartments.
• Manufactured to meet standard dimensional and quality requirements for reliable use.

Who is this for: This BARTOO 2-inch aluminum spacer is for car enthusiasts, restorers, and mechanics who need extra clearance for aftermarket air cleaners or who want to fine-tune induction stack geometry on vehicles using carburetors with a 5-1/8" opening. It suits owners of classic V8s, street rods, and custom builds who want a durable, direct-fit spacer that preserves sealing and requires no major modifications. If you plan to install taller air cleaners, adjust intake height, or resolve interference without changing your carburetor, this spacer is intended for your application.
