Skunk2 B-series vtec pro series 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 Valve Springs for Honda’s B-series VTEC engines are simply the best. Pro Series Valve Springs have been tested at speeds as high as 11,000 rpm on both the engine dyno and the street and our superior, Japanese-milled, super-clean chrome silicone wire is 100-percent eddy-current inspected prior to coiling and then heat-treated, shot-peened, and chemically polished for strength and durability. A special nitriding process concludes Skunk2’s rigorous manufacturing process. The end result is a lightweight valve spring that safely accommodates high-lift camshafts and features superior resistance to load loss, even under extreme operating conditions.
