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, replacing a damaged plate, or upgrading a performance setup, this kit provides the exact OEM-equivalent part that Holley carburetors demand for smooth, responsive throttle response.

Manufactured from steel for durability and thermal stability, this throttle plate kit features a 0.093-inch hole specification that ensures proper pivot alignment and consistent blade rotation under load. The kit includes the plate itself, mounting gasket, and fastening screws—everything needed for a complete, leak-free installation without sourcing hardware separately. Steel construction resists warping from fuel heat and carburetor operating temperatures, critical for maintaining precise metering control over extended use. The gasket prevents 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 using the supplied screws and gasket. Weighing just 0.19 pounds, the entire kit fits easily in your toolbox. Proper throttle plate function directly impacts cold start behavior, idle stability, and mid-range throttle feel, making this a worthwhile investment for any serious carburetor rebuild or tuning project.
