Product info below: Harmonics or high frequency fatigue is present in all racing engines and will usually destroy the valvetrain if not controlled. Properly designed valve springs will control the dominant harmonics, provide the needed stability, and reduce valvetrain component wear. Ferrea valve springs are developed from high strength alloys, including premium grade chrome silicon steel.

Our springs are heat-treated and stress relieved, which dramatically increases the springs life. Ferrea valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for todays aggressive valvetrain combinations. Ferreas wide range of retainers are available for Domestic, Sport Compact and Motorcycle markets. We currently offer four different types of retainers to choose from: Titanium, Lightweight Tool Steel, Steel and Aluminum Magnesium retainers, all of which are CNC machined to perfection and offer superior strength and stability.

Ferrea takes great pride in offering premium quality Spring Seat Locators. Fully CNC machining in-house from 4140 chromoly alloy for different applications. Each piece is crafted to exact tolerances OD & ID specs and insure flat, parallel spring pad to the bottom surface. Heat treatment consists of a hard Nitrided surface for unmatched toughness and anti-wear characteristics.
