Throttle Plate Kit

The Holley Throttle Plate Kit (HLY26-95) is a precision carburetor component designed for builders and mechanics restoring or tuning classic carburetors and custom engine builds. This 1-11/16 inch OD throttle plate serves as the flow-control butterfly valve inside your carburetor, regulating air intake as the driver modulates throttle input. Whether you're rebuilding a worn carb or replacing a damaged plate, this kit provides an OEM-equivalent part that Holley carburetors demand for smooth throttle response.

Manufactured from steel for durability and thermal stability, this throttle plate kit features a pivot hole diameter of 0.093 inches, ensuring proper pivot alignment and consistent blade rotation under load. The steel construction resists warping from fuel heat and carburetor operating temperatures, which is critical for maintaining precise metering control over extended use. The included gasket helps prevent vacuum leaks at the carburetor base, preserving idle quality and throttle transition smoothness.

This kit is essential for Holley carburetor users—particularly those running 4-barrel or performance carbs on street rods, muscle cars, and vintage restorations. Installation is straightforward for experienced mechanics: remove the old plate, clean the bore, and bolt the new assembly in place. Ensure you have any additional components needed for your specific application to achieve optimal performance.
