Expected to become the new standard in high performance valve spring design, COMP Cams(R) Conical and Dual Conical Valve Springs utilize round wire and feature a diameter-driven and progressive- pitch-driven natural frequency. This design increases the valve train RPM limit while reducing resonance concerns and decreasing dynamic spring oscillations. The result is longer spring life and the ability to run more aggressive camshafts. A breakthrough in valve spring development, COMP Cams(R) is the very first to market with this advanced conical design.

COMP Cams manufactures truly superior hydraulic and solid flat tappet, hyd and mechanical roller, and overhead camshafts for everything from OE replacement to full race, designed and manufactured using cutting-edge technology and the finest engineering in the industry. Whether your engine is naturally aspirated, or you run nitrous, or a supercharger or turbo, our cams make more horsepower than any other. Looking for that ultimate hard-hitting muscle car idle? Check out our aggressive new Thumpr Cams. Match our camshafts up with our competition-grade lifters, valve springs, timing sets, and other supporting components, and you'll experience the ultimate in race-winning reliability!
