Ferrea Valve Spring Kits bring together some of the best valvetrain components to help maximise performance specific to your engine application. Ferrea knowledge and expertise have allowed them to build valve spring kits using components of premium quality and durability that exceed standard industry requirements.

• Valve Springs – Ferrea Valve Springs provide the stability needed for high lift, high RPM racing engines, while minimising the load loss for today’s aggressive valvetrain combinations. Ferrea springs are heat-treated and stress relieved, which dramatically increases the spring’s life.
