Description
Precise secondary throttle actuation is critical for consistent carburetor performance and predictable engine response across the RPM band. The Holley Pro-Series Secondary Linkage 20-122 delivers the mechanical reliability and adjustability required to dial in optimal fuel metering as engine load increases. Built from stainless steel and engineered for direct bolt-on installation, this linkage eliminates sloppy secondary transitions and gives you the tuning control that separates competitive builds from the rest.
