Moroso 4500 Holley/King Demon Throttle Return Spring Kit - Carburetor Mount

Moroso is well-known for making performance parts that help racers and hot rodders get the most out of their engines. This throttle return spring kit is designed to work with Holley and King Demon carburetors, specifically models like the 4500 series. It ensures your throttle snaps back to idle reliably, which is crucial for safety and control, especially during spirited driving or racing.

This kit includes the necessary springs and hardware to properly set up your carburetor's return action. Having a strong, consistent return spring is important for preventing unintended acceleration and ensuring your engine responds predictably. It's a simple but vital component for any performance carburetor setup where a factory-style return spring might not be sufficient or properly configured.
