Pro Series Valves
Pro Series Valves
Manufactured from lightweight, EV8 stainless steel one-piece forgings, Skunk2’s Pro Series Valves are heat-treated using a proprietary process for extraordinary strength and durability. Other valves may appear similar, but only Pro Series Valves feature specially designed valve head profiles to optimize airflow. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. During development, each valvetrain component is tested both on the dyno and the road, including 11,000 rpm drag racing engines and 17,000 rpm superbikes. Manufactured from the best materials available, Skunk2 valvetrain components provide exceptional performance, reliability, and quality and remain standard-issue on each Skunk2 vehicle that we build and support.
