Description

MHS / PAC RPM Series Stage 3 5.0L Coyote Valve Springs 
 
The MHS / PAC Stage 3 Valve Springs for the 5.0L Coyote are a designed for Forced Induction applications with aftermarket camshafts. These Valve Springs are capable of handling .575" Lift. We suggest VCT Lockouts be used with these springs for maximum reliability. We suggest these for applications running up 30lbs of boost. For more than 30lbs of Boost or 8500 RPM, we suggest the Stage 4 RPM Series Springs. 
 
100% Made in the USA. The finest quality Valve Springs 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.
