KIBBLEWHITE Spring Kit - Steel 80-81700

If you're running a high-lift cam or boosted engine, your stock valve springs simply won't survive sustained RPM. The Kibblewhite Spring Kit steps up valvetrain control with CNC-machined titanium retainers and dual Cr-Si springs engineered to handle forced induction and aggressive cam profiles without valve float or coil bind. This is the foundation of a reliable, high-revving engine build.

Whether you're tuning a turbocharged platform or maximizing a performance camshaft, this kit delivers the spring rates and component quality needed to keep your valvetrain stable under extreme conditions.
