Ferrea 1.600in to 1.650in Dia 1.064/1.624 OD 0.760/1.164 ID Dual w/Damper Valve Spring - Set of 16

This is a set of 16 Ferrea dual valve springs, designed for high-performance engine builds where precise valve control is critical. These springs feature a dual-rate design with an integrated damper to manage harmonics and prevent valve float at high RPMs. The specific dimensions, including a 1.600in to 1.650in outer diameter range and 1.064/1.624 inch OD, along with 0.760/1.164 inch ID, are engineered to work with specific camshaft profiles and cylinder head configurations.

Ferrea is well-known for producing well-built engine components, and these valve springs are no exception. They are constructed from high-tensile spring wire, heat-treated and stress-relieved to ensure consistent performance and durability under demanding conditions. The dual-rate design allows for a softer seat pressure to reduce wear on valvetrain components during lower RPM operation, while providing a much stiffer open pressure to keep the valves firmly seated during aggressive acceleration and high-speed runs. The included damper is crucial for controlling spring surge and resonance, which can lead to valve float and potential engine damage at higher engine speeds.

When rebuilding or modifying an engine for performance, selecting the right valve springs is paramount. These Ferrea springs are intended for builders who understand the importance of matching spring specifications to camshaft lift, duration, and intended engine use. Ensure you consult your camshaft manufacturer's specifications to confirm compatibility with this spring set, as incorrect spring selection can lead to valvetrain instability or component failure. This set includes all 16 springs needed for a V8 engine.
