Ferrea 1.225in to 1.570in Diameter 1.005/1.53 OD 0.73/1.11 ID Dual w/Damper Valve Spring - Set of 16

Ferrea is well-known for making high-performance engine components, and this set of dual valve springs with dampers is a prime example of their work. If you're rebuilding or modifying an engine where valve control is critical, these springs are built to handle the demands. They feature a dual spring design with an integrated damper to help control harmonics and prevent valve float at higher RPMs.

This set includes 16 springs, enough for a typical V8 engine. The springs are constructed with durable materials designed for consistent performance under stress. The dual spring setup offers increased seat pressure and open pressure compared to single springs, which is important for keeping the valves seated properly during aggressive camshaft operation or high-speed engine use. The damper helps reduce spring surge, leading to more stable valve train operation.
