Ferrea is one of the most known names when it comes to valvetrain. That is because they make the finest quality valvetrain available! Ferrea is trusted by the top racing teams around the world. Formula 1, NASCAR, Indy, drag racing, and road racing teams all utilize Ferrea in the world's highest performing engines. It is definitely a notch above the rest. Heavy duty valve springs will prevent valve float at higher rpm. Titanium retainers will help keep the weight down, while providing extra strength. Valve springs and retainers are a MUST for high revving engines!
