SECTION 7
NITRIDED VALVES
  • One-piece stainless-steel, stellite-tipped valves impregnated by a special nitrided process with .002”
  • depth and .0002” surface buildup to improve wear properties and reduce friction
  • This process provides resistance to corrosion; wears superior to hard chromium and electrolysis
  • nickel-plating
  • Lightweight with profiles that provide excellent flow characteristics
  • Compatible with leaded and unleaded fuels and can be run in cast iron- and bronze-type guides at close tolerances
  • for maximum oil control and heat dissipation
  • Sold each
  • Made in the U.S.A.
  • FOR 05-17 88”/96”/ 103” TWIN CAM
