Product Details
Ferrea is known for making well-built engine components, and this dual valve spring with a damper is no exception. This spring is designed to handle the demands of performance engine builds, helping to ensure your valves close reliably under high RPMs and increased cam lift. The dual spring design offers improved stability and control compared to single springs, while the integrated damper helps reduce harmonic vibrations and potential spring surge, which can lead to valve float.
This particular spring has an outer diameter ranging from 1.065 to 1.625 inches and an inner diameter from 0.77 to 1.175 inches, with a free height that allows for a seat pressure suitable for many performance applications. It's built to fit valve spring diameters between 1.600 and 1.650 inches. This is a single spring intended for the 'D/S Only' position, meaning it's designed for a specific side of the engine or valve train setup, so be sure to order the correct quantity for your application.
