KIBBLEWHITE Valve Spring Kit 30-30720

Valve spring failure is one of the quickest ways to turn a race day into a nightmare—and stock springs simply aren't engineered to handle sustained high-RPM loads or aggressive cam profiles. The KIBBLEWHITE Valve Spring Kit 30-30720 gives you OEM-quality components built to last, with premium materials and precision engineering that keeps your valve train reliable whether you're on the track or the street. This complete kit arrives ready to install, eliminating guesswork and ensuring proper fitment for your application.

What sets KIBBLEWHITE apart is their commitment to American manufacturing and material science. Each spring set is paired with titanium upper collars to reduce reciprocating mass, while keepers and lower collars are included as required for your specific engine. You get a choice between Black Diamond™ valves (stainless steel with stellite tips and special impregnation for superior wear resistance) or White Diamond® valves (hard chrome stems for reliable durability), depending on your performance demands.
