4-Hole Carburetor Spacers: Divided spacers that maintain intake velocity for better mid-range torque
Tapered Spacers: Transition spacers for carburetor-to-manifold size mismatches
Phenolic Spacers: Heat-insulating spacers to reduce fuel temperature and prevent vapor lock
Aluminium Spacers: Lightweight metal spacers for maximum airflow

Carburetor Mounting Hardware

Carburetor Stud Kits: Stainless steel and ARP stud kits for secure carburetor mounting without stripped threads
Carburetor Gaskets: Base gaskets, spacer gaskets, and fuel inlet gaskets for leak-free installation
Carburetor Nuts & Washers: Stainless steel hardware for professional installation

Carburetor Fuel Line Components

Carburetor Fuel Line Kits: Complete braided hose and AN fitting kits for professional fuel line plumbing
Fuel Inlet Fittings: AN and NPT fuel inlet fittings in various angles and sizes for custom fuel line routing
Fuel Line Adapters: AN to NPT adapters and reducers for carburetor fuel connections

Air Cleaners & Filters

Air Cleaner Assemblies: Chrome and polished aluminium air cleaners in round, oval, and triangular styles
Air Filters: High-flow panel and element filters for carburetor applications
Pod Filters: Low-profile cone filters for custom air cleaner setups and velocity stacks
Air Cleaner Studs & Hardware: Wing nuts, washers, and mounting hardware for air cleaner installation

Carburetor Linkage & Cables

Throttle Cable Brackets: Billet aluminium brackets for precise throttle cable routing and adjustment
Throttle Return Springs: Heavy-duty springs for positive throttle return and safety
Throttle Linkage: Ball studs, clevis pins, and linkage rods for custom throttle setups
Kickdown Cables: Transmission kickdown cables and brackets for automatic transmissions

Why Upgrade Carburetor Accessories?

Proper carburetor accessories are essential for reliable performance and maximum power. Carburetor spacers increase plenum volume and improve airflow distribution, typically adding 5-15 horsepower on V8 engines. Quality mounting studs prevent stripped threads and ensure secure installation. Professional fuel line kits with braided hose and AN fittings eliminate leaks and provide clean, reliable fuel delivery. High-flow air filters and cleaners reduce restriction while protecting your engine from contamination.

Carburetor Spacer Selection Guide

Spacer Height: 1/2" spacers provide minimal plenum volume increase and work well for street applications. 1" spacers improve mid-range torque and are ideal for most performance builds. 2" spacers maximize top-end power but may reduce low-end response—best for race engines operating at high RPM.

Open vs 4-Hole Spacers: Open spacers flow more air and increase top-end power but may hurt low-RPM performance. 4-hole spacers maintain intake velocity for better throttle response and mid-range torque. Choose based on your engine's operating range and intended use.

Material Selection: Aluminium spacers provide maximum airflow and are lightweight. Phenolic (plastic) spacers insulate heat from the intake manifold, reducing fuel temperature and preventing vapor lock in hot climates or under-hood conditions.

Installation Tips

Spacer Installation: Always use proper gaskets above and below spacer. Torque carburetor mounting studs/bolts evenly in cross pattern to prevent warping. Verify throttle linkage clears spacer and operates smoothly through full range.

Stud Kit Installation: Chase threads in intake manifold with proper tap before installing studs. Apply thread locker to stud threads going into manifold. Install studs finger-tight plus 1/4 turn—do not over-tighten.

Fuel Line Routing: Route fuel lines away from exhaust heat and moving components. Use proper AN wrenches to avoid damaging fittings. Test all connections for leaks before starting engine.

Air Cleaner Clearance: Verify adequate clearance between air cleaner and hood/bonnet. Ensure air cleaner element seals properly to prevent unfiltered air entering carburetor.
