Ferrea 1.225in to 1.570in Dia 1.04/1.56 OD 0.74/1.145 ID Dual w/Damper Valve Spring - Set of 16

Ferrea dual valve springs with damper, set of 16. These springs are designed for high-performance engine builds where precise valve control is critical. They feature a dual-spring design with an integrated damper to help manage harmonic vibrations and prevent valve float at high RPMs.

Each spring in this set is constructed from high-strength steel, a well-built material chosen for its ability to withstand the extreme stresses of aggressive camshaft profiles and high engine speeds. The springs have an outer diameter ranging from 1.570 inches down to 1.04 inches, and an inner diameter from 1.145 inches down to 0.74 inches. This specific sizing and dual-rate design allow for controlled valve motion, reducing the risk of valve-to-piston contact and ensuring reliable operation under demanding conditions. The inclusion of a damper is a notable feature that further enhances stability by absorbing excess energy within the spring assembly.

This set includes 16 individual valve springs, enough for a complete V8 engine. When rebuilding or upgrading a performance engine, selecting the right valve springs is crucial for achieving optimal power and durability. Ferrea is known for producing robust components for serious engine work, and this dual spring set with damper is a solid option for those pushing their engine's limits.
