Aluminum Throttle Plate Kit

The Holley Aluminum Throttle Plate Kit (Part No. 26-100) is a direct-fit replacement set designed specifically for Holley carburetors. This four-piece aluminum throttle plate kit includes all necessary mounting screws and is engineered to maintain precise fuel-air metering and throttle response in high-performance carburetor applications. The 2-inch outside diameter throttle plates are sized to match OEM Holley carburetor specifications, making this kit the correct choice for rebuilds, replacements, or performance tuning work on compatible Holley four-barrel and two-barrel carburetor models.

Aluminum construction provides a lightweight, corrosion-resistant alternative to steel plates while maintaining the dimensional accuracy required for proper carburetor operation. The included screws ensure you have all hardware necessary for installation without sourcing additional fasteners. When throttle plates wear, stick, or become damaged, they create stumbling, hesitation, or unpredictable idle behavior—replacing them with factory-specification Holley parts restores smooth throttle modulation and consistent engine response. This kit is essential for anyone restoring a Holley carburetor to original function or upgrading to a higher-flowing Holley model on a classic or performance vehicle.

Carburetor enthusiasts and engine builders rely on OEM-specification throttle plates to ensure proper fuel atomization and throttle transition. Whether you're rebuilding a street-driven classic, preparing a show engine, or tuning a dedicated performance carb, the Holley 26-100 kit provides a straightforward, verified solution. Keeping a spare set on hand is common practice in shops and garages, since throttle plate replacement is often needed during full carburetor overhauls or when upgrading to a larger Holley unit.
