Hamilton Cams Valve Springs, Dodge (1998.5-18) 5.9L & 6.7L Cummins, 110lb (Over 4500 RPM)

This is the high RPM version of the 24v 103lb spring. Triple Shot peened and stress relieved. If you are running over 4,500 rpm and have a cam with over 0.320" lobe lift, then we suggest these springs with light retainers. Use Titanium retainers for cams with over .370" lift. As a precautionary measure, please inspect titanium retainers after every season for wear.
