The 4500 Throttle Return Spring Kit in Blue from CVR Performance is designed for high-performance carburetors and fuel injection systems, ensuring reliable throttle response and positive return action. This kit is essential for applications in drag racing, street performance, and engine swaps where factory or worn springs may fail to provide consistent idle recovery and full throttle lockout.
Engineered with precision-wound spring steel, this throttle return spring kit is calibrated to deliver optimal tension across the full throttle range, preventing throttle blade stiction and ensuring a smooth return to idle. The blue finish features a hard-anodized protective coating that resists corrosion and heat cycling in engine bay environments.
This kit is ideal for experienced mechanics and engine builders working on vintage hot rods, LS swaps, and Holley-based fuel systems, where OEM springs may lack the durability needed for repeated track use or high-temperature conditions.
