MHS / PAC RPM Series GEN 3 Coyote / 5.2L GT350 Voodoo Valve Springs 
 
You asked for it, we listened! Here is the MHS / PAC RPM Series Valve Spring Kit for the GEN 3 Coyote and 5.2L Voodoo Cylinder Heads. These Valve Springs are 100% Made in the USA and are the finest quality Valve Springs available for the GEN 3 / GT350 Engines. 
 
These Springs use the Stock Installed Height of 1.800" and have 85lbs of Seat Pressure. The good thing about having a taller spring, means you typically will have more coil bind clearance. At 1.800", these springs have just over .200" of coil bind clearance at .600" Lift. This means we can shim them up if your application calls for more seat pressure. 
These Valve Springs are supplied with our 4130 Chrome Moly Retainers. We also have an option to include a set of 32, .060" Shims. The .060" shims will add 15lbs of seat pressure for 100lbs at 1.740" Installed Height. 100lbs of seat pressure is good for at least 30lbs of boost at 9000 RPM from what we have seen. 
 
Please see Spring Spec Chart for complete pressures and details.
