What is the purpose of dual valve springs?

Dual valve springs provide increased stability to the valve train, especially at higher engine speeds. This helps prevent valve float, ensuring that the valves close properly and consistently, which is crucial for engine performance and longevity.

What kind of engine builds are these springs best suited for?

These springs are designed for high-pressure applications, making them ideal for GM L5 engines that are being upgraded with performance camshafts featuring aggressive lift profiles or for engines utilizing forced induction like turbochargers or superchargers.

Do these springs come with retainers or locks?

This set includes 20 dual valve springs. It is recommended to check the product details or consult with a specialist to confirm if retainers, locks, or other necessary valve train components are included or need to be purchased separately for your specific build.

Product Details

Built with a specific spring rate of 350 lbs. at the valve seat and 950 lbs. at the full lift, these Ferrea GM L5 High Pressure Dual Valve Springs are made for demanding engine builds. The dual spring design offers excellent stability, especially at higher RPMs, helping to prevent valve float and ensure consistent valve train operation. This set includes 20 springs, enough for a complete V8 engine.

Ferrea uses high-grade steel alloys for their springs, heat-treated and stress-relieved to ensure they hold their intended pressure over time and under extreme conditions. This attention to material and manufacturing detail means you can rely on these springs to perform consistently, whether you're on the track or pushing your engine hard on the street. They are designed to work with specific L5 engine configurations where increased spring pressure is required for camshafts with aggressive lift profiles or for forced induction setups.

When rebuilding or upgrading your GM L5 engine's top end, especially with a performance camshaft, these Ferrea valve springs are a solid choice. They are designed to handle the increased demands of higher lift and longer duration camshafts, ensuring your valves close reliably and preventing potential piston-to-valve contact. Always consult your camshaft manufacturer's specifications to ensure these springs meet the required seat and open pressures for your specific build.
