About This Product
These are two brand-new Holley white light vacuum secondary diaphragm springs (part #20-13). If you're tuning a Holley carburetor, these springs control how quickly the secondaries open – the white light spring is a common choice for street performance, giving a smooth, gradual throttle response. Made in the USA and sold with a manufacturer warranty. Perfect for tweaking your carb's behavior without spending a lot. Whether you're building a hot rod, restoring a classic, or just fixing up your ride, these little springs make a big difference. Easy to install if you're familiar with carb internals. A must-have for Holley enthusiasts who want to dial in their setup just right.Product Information
