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 titanium retainers are CNC-machined in-house from certified medical grade titanium that is milled in the USA. Skunk2 retainers are designed to significantly reduce overall valve train mass and are machined to extremely close tolerances in order to ensure properly installed spring heights and pressures. Skunk2 has been supplying titanium retainers to professional race cars and street cars for nearly a decade, and are used on all Skunk2 race and project cars.
