Skunk2 Racing valve springs have been developed as a result of our experiences in drag racing and touring car racing. Tuner Series springs are made from super clean chrome silicone wire milled in Japan. By using inner and outer valve springs with very different natural frequencies and also using a slight interference fit between the two springs, tuner series valve springs prevent valve float and maintain valve train stability at over 10,000 RPM's. Tuner Series valve springs are designed for use with Skunk2 Ti Retainers on Street/Race vehicles running moderate to high lift cams.

Skunk2 designs, develops and tests all of our valve train components in-house to ensure the highest quality and greatest performance gains. During development, all valve train components are tested in engines both on the dyno and on the road. Manufactured from the best materials available, our valve train components provide exceptional performance, reliability, and quality. Skunk2 valve train components are standard issue on all the project cars and race cars we build and support, and are available in our premium Pro-Series line and our Tuner Series line, both offering exceptional performance, reliability, and quality.

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.
