Description

Ferrea Valve Springs are the top of the line when it comes to valve train. We use them in Ferrea's cars and suggest them to Ferrea's customers. They are only to be used with Ferrea Retainers.

Ferrea Retainers are precision machined to be as light as possible without compromising strength. They are only to be used with Ferrea Valve Springs.

Ferrea Valve Spring Seat Locators are precision machined to be as light as possible without compromising strength. They are only to be used with Ferrea Valve Springs.

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. Ferrea's springs are heat-treated and stress relieved, which dramatically increases the springÆs life. Ferrea's valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for todayÆs aggressive valvetrain combinations.

Ferrea is pleased to offer Ferrea's Pro-Series Titanium Retainers including sizes that fit both traditional Domestic springs and Sport Compact springs. Precision CNC-machined from aerospace quality titanium, these Pro Retainers are fully heat-treated and finished to exact tolerances, adding strength while offering a 40% weight reduction over conventional steel retainers. We have available applications for 6, 7, 8 (super 7) and 10 degrees. Examine the overall quality of FerreaÆs Pro-Series Retainers and see why professional engine builders demand Ferrea Racing Components.

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.
