Holley 20-53 390 465 570 600 670 750 Vacuum Secondary Connecting Rod Link

• Vacuum secondary connecting rod links the throttle shafts correctly so the secondaries open smoothly.
• A fresh rod and split pin helps remove slop from worn linkage and improves consistency.
• Designed to suit Holley vacuum secondary carburettor series listed in the reference.

Holley vacuum secondary carbs rely on a simple mechanical link to keep everything moving in the right order, and wear or missing hardware can lead to inconsistent secondary opening and a soft throttle feel. Replacing the connecting rod is an easy fix during a service, especially if you are already working on diaphragms, springs or secondary tuning. Match the rod style to your carb family and verify free movement after fitting.
