Ferrea Valve Springs - Acura/Honda

Our New Ferrea Valve Springs are processed with premium-grade alloy and feature special
thermal treatment. Our advanced spring design and material specifications, have uniform load
& stress distribution even in the most extreme racing environment. This New Valve Spring
offers customers additional durability in all high revving applications at an affordable price.
  • Developed from high strength alloys
  • Springs are heat treated and stress relieved = increase in spring's life!
  • Provide stability needed for high lift and high RPM.
  • Minimizes load loss for today's aggressive valvetrain combo's.

"Harmonics or high frequency fatigue is present in ALL racing engines and will usually destroy the valvetrain if not controlled! Properly designed valve springs will control the dominant harmonics, provide the needed stability, and reduce valvetrain component wear."

IMPORTANT: All Valve Springs require Retainers and Spring Seat Locators. See requirements listed under Part #'s.
