Valvetrain

All valve seals are made for long life Meet or exceed OEM specifications When using Kibblewhite spring kits, Kibblewhite valve seals must be used because of spring clearances Made in the U.S.A.

By taking advantage of the latest development in valve spring wire chemistry and manufacturing techniques, By coupling these developments with strict KPMI® design protocols and employing multiple design simulation and FEA analysis software, we...
