The Hamilton Cams 07-S-009T High RPM Springs & Titanium Retainers are perfect for use in 1998.5-2017 Dodge 5.9L /6.7L Cummins engines running over 4500 RPM. This high RPM version of the Hamilton 103# spring is triple shot peened and stress relieved. If you have a cam with over .370" lobe lift, the titanium retainers are recommended.
