Maximize your N55 or S55 engine's performance with Ferrea Valve Springs and Retainers, precision components crafted from chromoly alloy. These springs undergo special thermal treatment, ensuring exceptional durability even in extreme racing conditions. Addressing issues like valve binding, breakage, and float, Ferrea valve springs are meticulously heat-treated and stress-relieved, providing stability for high-lift and high-RPM racing engines while minimizing load loss. Precision CNC machined titanium retainers offer superior strength and stability. Ferrea's Spring Seat Locators, made from 4140 chromoly alloy, guarantee precise tolerances and a flat, parallel spring pad with a hard Nitride surface treatment for exceptional toughness and anti-wear characteristics. Please note that installation requires the expertise of an engine builder.
