You asked for it, we listened! Here is the MHS / PAC RPM Series Competition Valve Spring Kit for the GEN 3 Coyote and 5.2L Voodoo / Predator 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.

This Valve Spring Kit is designed specifically for High RPM, Competition Builds where shift points will be upwards of 9K RPM and boost pressures will be upwards of 35lbs. Will support 10K RPM and 50lbs +.

Fits Stock Valve Seals - Drop in design
117lbs Seat Pressure @ 1.800" Installed Height

*Stock sized secondary chains, regardless of brand, will not last with the increase in spring rate and nose pressure. You MUST run an aftermarket big chain secondary drive or you will have a secondary chain failure at some point.

We highly recommend using RGR Secondary Chain, Sprocket and Tensioner Kit with these springs.

Please see Spring Spec Chart for complete pressures and details.
