Product Details
Ferrea is well-known for making high-performance engine components, and this dual valve spring, part number S10030-1, is no exception. This spring is designed with a damper to help control valve float, which is crucial for maintaining engine stability at higher RPMs. It features a dual spring design, meaning it uses two springs working together to provide the necessary force to close the valve quickly and reliably.
The spring has a tapered design, going from 1.225 inches on the inside diameter to 1.570 inches on the outside diameter. This unique shape, along with the damper, helps to reduce resonance and vibration within the spring itself. This can lead to improved valve train stability and longevity, especially in applications where the engine is pushed hard. The 'Sngl (D/S Only)' designation indicates it's a single spring set intended for the driver's side, so be sure to order the correct quantity for your application.
