Ferrea
Valve Springs - BMW
For ALL racing environments!
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." (Ferrea catalog, '03)
IMPORTANT: All Valve Springs require
Retainers and Spring Seat Locators. See requirements listed under Part
#'s.
