Skunk2 designs, develops and tests all valvetrain components in-house to ensure the highest quality and greatest performance gains. During development, all valvetrain components are tested in engines both on the dyno and on the road. Manufactured from the best materials available, Skunk2 valvetrain components provide exceptional performance, reliability, and quality. Skunk2 valvetrain components are standard issue on all the project cars and race cars we build and support.
Skunk2 Pro-Series valve springs are simply the best valve springs in the sport compact market. Pro-Series valve springs are designed to handle the demands of extreme lift camshafts running at the prolonged high rpms of professional championship level racing. We have tested the Pro-Series valves springs up to 11,000 rpm. The Japanese milled super clean chrome silicone wire is 100% eddy-current inspected before coiling. After the spring is coiled, it is heat treated, shot-peened, and further enhanced with an advanced proprietary chemical polishing and nitriding process.
The end result is a lightweight valve spring that will safely accommodate high lifts and has superior resistance to load loss even under extreme operating conditions. This type of performance is only possible because of the additional processing and stress relieving that goes into Pro-Series valve springs allowing us to use less coils. The Skunk2 Pro-Series valve spring is the only valve spring designed for use with Skunk2 Pro-Series camshafts.
