Skunk2 Pro Series VP Valve Springs:
Designed to handle the demands of extreme-lift camshafts operating at prolonged, high-rpm use at championship-level racing, Skunk2’s Pro Series XP Valve Springs are simply the best. Each Pro Series XP Valve Spring application has been tested at speeds as high as 11,000 rpm on both the engine dyno and the street. 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. 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.
Skunk2 Pro Series Titanium Retainers:
Skunk2’s industry-leading Pro Series Titanium Retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Unlike other retainers, Skunk2 Titanium Retainers feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction.
