KIBBLEWHITE Spring Kit 40-41600

If you're running a forced induction setup or high-lift cam profile, stock valve springs will cost you reliability and peak power. The KIBBLEWHITE Spring Kit 40-41600 delivers the valvetrain control needed to safely maximize RPM without float or valve seat separation. Built with CNC-machined titanium retainers and premium Cr-Si dual springs, this kit handles aggressive boost and high-rpm demand that stock components simply can't sustain.
