BARTOO Aluminium Carburetor Spacer 1" for 5-1/8" Opening — CNC-Machined, Sealed Fit

BARTOO's 1-inch aluminum air cleaner spacer raises a 5-1/8-inch carburetor opening to create space for taller air cleaners, velocity stacks, or gaskets while providing a durable, sealed connection.

If your classic V8 or SBC/BBC build needs added clearance between the carburetor and air cleaner, a precision spacer is a simple, reversible solution. This one-inch spacer from BARTOO is CNC-friendly aluminum made to match common 5-1/8-inch bolt patterns used by Holley, Edelbrock, Rochester, Demon, Carter and similar carburetors. It’s designed to install quickly, maintain a solid seal, and accept standard gaskets and stud patterns so you can restore fitment without cutting or modifying your intake or air cleaner.

How does this spacer affect carburetor and air cleaner fitment?

The spacer increases vertical clearance by one inch, making room for taller aftermarket air cleaners, dual-plane carb hats, or custom velocity stacks. It aligns with the 5-1/8-inch bolt pattern and keeps mounting studs centered for a straightforward swap.

• One-inch thickness provides consistent clearance for taller filters and accessories.
• Designed for 5-1/8" carburetor openings used by major brands.
• Maintains standard stud and gasket locations for easy installation.

Will this spacer fit my Holley, Edelbrock, or Rochester carb?

Yes—the spacer is made to match the common 5-1/8-inch opening found on many Holley, Edelbrock, Rochester, Demon and Carter carburetors. It’s a universal-style part intended to replace or duplicate factory spacer dimensions so it works with widely used intake and air-cleaner setups.

• Compatible with Holley, Edelbrock, Demon, Carter, Rochester-type carbs using 5-1/8" openings.
• Works with SBC and BBC riser applications when that bolt pattern is present.
• No trimming required for standard installations—direct replacement design.

What material and sealing features does the spacer use?

Constructed from high-quality aluminum, the spacer offers stable mechanical performance and resists corrosion compared with lower-grade metals. The machined faces provide a flat sealing surface; pairing the spacer with proper gaskets ensures a reliable air and vacuum seal at the carburetor base.

• High-grade aluminum body for lightweight strength and long service life.
• Machined mating surfaces to support effective gasket sealing.
• Compatible with standard carburetor gaskets and studs for leak-free installation.

How simple is installation and what do I need to know before fitting?

Installation is straightforward for anyone familiar with carburetor removal and reassembly. Remove the air cleaner and carburetor (or lift on cars with stud-mounted carbs), place the spacer with a gasket between carb and intake or between carb and air cleaner as needed, then re-torque to factory specifications.

• Fits as a direct replacement—no drilling or modification required for matching bolt patterns.
• Use correct gaskets and torque sequence to prevent leaks or warping.
• Check stud lengths and nut clearance when adding the spacer plus a taller air cleaner.

Who this spacer is for: Enthusiasts restoring classic muscle cars, hot-rodders modifying air-cleaner height, and mechanics swapping aftermarket filters will benefit from the BARTOO 1-inch aluminum spacer. It’s aimed at anyone needing a reliable, reversible way to gain clearance on carburetors with a 5-1/8-inch opening while keeping installation simple and reversible. If you require a lightweight, corrosion-resistant spacer that matches common carburetor bolt patterns, this part is a practical choice.
