1-3/4in SS Throttle Plates (4 Pack)

The 1-3/4in SS Throttle Plates (4 Pack) from Quick Fuel Technology are precision-engineered replacement components designed for carbureted performance engines where exact fuel metering and air delivery demand factory-spec accuracy. Built as a matched set of four, these stainless steel throttle plates address the core need in carburetor tuning: maintaining consistent, repeatable throttle response across all four barrels or stages of your fuel delivery system. Whether you're restoring a classic muscle car, rebuilding a high-performance street engine, or fine-tuning a competition carb, throttle plate wear or damage directly impacts drivability, idle quality, and fuel economy.

Constructed from stainless steel, these 1-3/4 inch outside diameter throttle plates resist corrosion and maintain dimensional stability under thermal cycling—critical for engines that see serious heat cycles or prolonged storage. The OD dimension ensures compatibility with Quick Fuel carburetor bodies engineered to this specification, while the material choice eliminates rust and binding issues common to mild steel originals. Each plate in the four-pack is matched for balance, preventing stumble, hesitation, or lean-condition cruising that plagues engines with worn or mismatched throttle plates. Proper throttle plate seating and alignment directly govern how cleanly your engine transitions from idle to cruise, affecting both responsiveness and fuel consumption.

Mechanics and engine builders working with Quick Fuel carburetors—including modern performance reproductions and competition applications—will find this four-pack essential for carburetor service, restoration, or performance optimization. Installation requires careful alignment of each plate with its corresponding shaft bore; improper seating or bent plates cause air leaks that ruin idle and throttle consistency. This product is ideal for anyone rebuilding a classic carburetor, upgrading from worn OEM plates, or standardizing components across multiple matching carbs. Check your carburetor's OD bore specification before ordering to confirm compatibility with the 1-3/4 inch dimension.
