COMP Cams titanium valve spring retainers for double valve springs will often allow you to gain speed and power because titanium retainers are lighter and stronger than most steel ones. Additionally, our Super Lock titanium design gives you confidence; no longer will you be preoccupied with splitting a retainer and tearing up an engine when turning 10,000 RPM.
