BBTO Air Cleaner Riser Spacer Kit, 4-Piece — 5in 1/4" Stud with Stainless Stud & Black Spacers

BBTO's 4-piece air cleaner riser spacer kit provides a 5-inch, 1/4" threaded stud and three interchangeable spacers (1/2", 1", 1½") to raise and stabilize carburetor-mounted air cleaners.

This stainless-steel stud-and-spacer set is built for durability and a neat engine-bay appearance. It lets you fine-tune air cleaner height for clearance, airflow alignment, and personalization while replacing worn hardware with corrosion-resistant components. The kit includes one long stud and three different spacer thicknesses so you can mix-and-match heights without buying extra parts.

How does the BBTO riser spacer kit change air cleaner fitment?

The kit raises the air cleaner assembly off the carburetor using a single 5-inch stud and selectable spacers. Changing spacer combinations alters overall height quickly, helping clear linkages, hood fins, or aftermarket intake hardware without permanent modification.

• Includes 1x 1/4" threaded, 5" long stud for standard carburetor center holes.
• Three spacer thicknesses: 1/2", 1", 1½" for flexible stacking options.
• Swap or stack spacers to achieve custom heights for clearance and appearance.

What materials and finish does the kit use, and why does that matter?

The stud is stainless steel and spacers are finished in black/silver style for corrosion resistance and a cohesive look. Durable construction resists rust and repeated removal, so the hardware stays functional and visually consistent with engine components.

• Stainless-steel stud for strength and corrosion resistance.
• Black spacer finish to complement most air cleaners and engine bays.
• Hardware survives routine installation and shop environments.

How easy is it to install or swap spacers during maintenance?

Installation is straightforward: remove the old center nut/bolt, place the stud through the air cleaner and carburetor center hole, then add chosen spacer(s) and secure the nut. No special tools are required beyond common wrenches, and spacers can be swapped in minutes during routine service.

• Fits standard 1/4" center threads common on many carburetor-style air cleaners.
• Requires basic hand tools — wrench or socket to tighten the top nut.
• Perfect for quick height adjustments while tuning or swapping filters.

Will this kit work with aftermarket and OEM air cleaners?

Yes — the BBTO stud and spacer sizes are intended for widespread compatibility with many aftermarket and OEM round air cleaners that use a 1/4" center stud. Check your air cleaner's center hole and thread size to confirm fit before purchase.

• Designed for air cleaners using a 1/4" threaded center stud.
• Adjustable spacer stack adapts to varied aftermarket filter heights.
• Best for round, top-mounted carburetor air cleaner assemblies.

Who is this for: The BBTO 4-piece air cleaner riser spacer kit is ideal for classic car restorers, hot-rodders, small-engine mechanics, and anyone replacing or modifying a carburetor-mounted air cleaner.
