MHS / PAC RPM Series Stage 4 5.0L Coyote Valve Springs and Titanium Retainers

The MHS / 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. If you have a 5.0L Coyote and are planning on making over 30lbs of boost, this is the spring kit for you! We have tested these up to 48lbs of boost and 9500 RPM without any issues.

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. These Springs can be used with the Factory Retainers. We do have both 4130 Chrome Moly and 6AL-4V Titanium Retainers available as an upgrade.

Fits GEN 1 and GEN 2 Heads only, including Boss 302. Will not fit GEN 3 or Voodoo heads as they use a 1.800" Installed Height.
