Holley is the legendary American carburetor and fuel-injection brand — over 100 years of induction history. From the iconic 4150 four-barrel to today's Sniper EFI conversions, Holley remains the choice for muscle car restorations, Pro Mod, and gasser builds.
The secondary diaphragm is a critical component in your Holley carburetor, responsible for the smooth opening of the secondary butterflies. If your car hesitates or feels sluggish when you floor it, a torn or stiff diaphragm is often the culprit. The Holley 135-4 Vacuum Secondary Diaphragm is the perfect replacement, featuring high-quality rubber and steel construction to ensure reliable operation under varying vacuum conditions.
Don't let a small component ruin your driving experience. A properly functioning vacuum secondary system is essential for achieving the full power potential of your engine. By replacing your old, brittle diaphragm with this genuine Holley part, you restore the crisp, responsive acceleration your vehicle was designed to provide. This is a must-have item for any carburetor service kit. When you need the right parts to keep your engine running smoothly, you can count on the inventory and expertise at GGCRACING.
