The 2026 CL5 grind is designed for unrestricted classes where high-RPM stability and power matter most. Built to take advantage of modern rule packages that allow ported heads and billet rods, it pulls strong through the 7,000–7,200 RPM range. When paired with 10.8 lb valve springs, the CL5 maintains stable valve control at elevated RPM, delivering usable power where other cams fall off. Legal in AKRA, NKA, and WKA unrestricted stock classes.
