The CMS / PAC Stage 4 RPM Series Valve Springs are the ultimate valve springs for 5.0L Coyote. These springs are capable of handling extreme RPM and Boost Pressures! TI-VCT Lockouts must be used and upgraded timing chains and guides are suggested. These Springs fit the Stock Coyote Retainers but we also offer optional PACTuff 6AL-4V Retainers. If you have a 5.0L Coyote and are planning on making over 30lbs of boost, this is the spring kit for you!
 
100% Made in the USA by PAC Racing, these Valve Springs and Retainers are the finest quality available for the 5.0L Coyote Cylinder Heads.
