Description
If you’re running a high-lift camshaft or forced induction setup, your stock valve springs aren’t engineered to handle the sustained pressures at elevated RPMs. The KIBBLEWHITE Spring Kit 40-41400 delivers the valvetrain control and reliability you need to keep your engine performing consistently, whether you’re on the dyno or at the track. This is precision engineering designed specifically for boosted applications and performance-focused builds that demand more from every component.
