Ferrea produces these premium 7M valvetrain components for your high-performance upgrade project.
Titanium dual springs Support high-revving setups thanks to the reduced weight with the extra spring-rate to provide necessary tension. This is important for sufficient combustion chamber sealing, heat transfer and bounce prevention at high RPM, especially with aftermarket cams.

Tech notes from Ferrea: Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve. We, at Ferrea, are dedicated to providing the absolute best product on the market. Our extensive R & D programs provide tehcnological gains, which are implemented in each of our competiton plus valves. They are engineered for higt rpm, high horsepower racing engines, and are chose by many top NASCAR, Drag, and Oval & Sprint Car-racing teams.
To manufacture the valves we use special aerospace quality alloys, including EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminated any damage to the material structure. The valves are then heat treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip.
Our engineering staff at Ferrea spends countless hours conducting flow bench tests to achieve an optimum balance of flow, velocity and efficiency in the design of this valve. As a result, these valves incorporate smoother radiuses and unique undercuts.
These exclusive features are what make the Ferrea Competition Plus Valves unequaled in performance and reliability! |
