Oval track racing is lots of cars, wheel-to-wheel, racing around the track at high speeds. COMP Cams Oval Track Pro-Plasma nitrided camshafts can give you the performance that you need to steer into victory lane. These cams are designed for racing applications, plus, they've been given a Pro-Plasma nitriding process to increase hardness and durability. Nitrogen is introduced into the cam's metal for improved initial and long-term wear characteristics, and increased surface lubricity through reduced friction. Pro-Plasma is a race-proven black oxide finish with superior results. Oval track racing is definitely more than just making left turns. Pick a cam that can handle the stress--COMP Cams Oval Track Pro-Plasma nitrided camshafts.
