This COMP Cams valve spring kit is built for 2011–2014 and 2015‑later Ford Coyote and Boss 5.0L engines and is rated for up to .600" maximum lift. The beehive springs provide increased valve control at high RPM and higher load capacity versus stock springs, and the complete kit includes titanium retainers, seals and precision seats. It’s intended to support performance cams requiring greater lift and spring load.
