When choosing an upgrade to your current OEM valves and wanting to do so without compromising quality and reliability. Supertech's Street Performance valves are without a doubt the best bang for your buck!

All Supertech valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance & durability at high rpms. Using high quality steel alloy allso provides the added benefit of better structural memory for all of our springs.

Pro Series XP Racing Valve Springs are engineered to handle the demands of extreme-lift camshafts operating at prolonged, high-rpm use at championship-level racing. Skunk2’s Pro Series XP Racing Valve Spring’s for the Honda’s K-series i-VTEC engines are simply the best on the market. Pro Series XP Racing Valve Springs have been tested at speeds exceeding 11,000 rpm on our engine dyno, street, and the race track. Our superior, Japanese-milled, super-clean chrome silicone wire is 100-percent eddy-current inspected prior to coiling. Next, they are 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.
