Skunk2 designs, develops and tests all of their 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, their valvetrain components provide exceptional performance, reliability, and quality. Skunk2 valvetrain components are standard issue on all the project cars and race cars they build and support, and are available in their premium Pro-Series line and our Tuner Series line, both offering exceptional performance, reliability, and quality.

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 valvetrain stability at over 10,000 rpms. Tuner Series valve springs are designed for use with Skunk2 Ti Retainers on Street/Race vehicles running moderate to high lift cams.
