Throttle Spring 2 Pack

The LONGACRE Throttle Spring 2 Pack (part number 52-32500) is a matched pair of steel throttle return springs designed for performance automotive and racing applications. These chrome-plated springs restore proper throttle response and ensure consistent pedal tension across the carburetor or fuel injection system, making them essential replacement components for any engine rebuild or carburetor restoration project.

Chrome plating protects against corrosion and extends spring lifespan, particularly important in high-temperature engine compartment environments where bare steel would degrade rapidly. The two-pack configuration provides a matched set, ensuring uniform spring force across dual-carb setups or serving as a replacement pair with a spare. Steel construction maintains tensile strength under repeated cycling, critical for maintaining calibrated throttle feel and preventing stuck-throttle conditions that can occur with weakened or worn springs.

Throttle return springs are commonly replaced during carburetor restoration, fuel system upgrades, or routine engine maintenance on classic vehicles, hot rods, and performance engines. Worn springs frequently cause hesitation, sluggish throttle return, or inconsistent idle behavior. LONGACRE is a recognized manufacturer in the automotive performance and racing sector, offering components engineered for reliability under demanding conditions.

This throttle spring pair is a direct replacement or upgrade option suitable for carbureted engines and mechanical fuel injection systems. Verify fitment against your specific carburetor model or throttle linkage configuration before purchase, as throttle spring diameters and lengths vary by application.
