Features

  • Constructed of tungsten alloyed with chrome, molybdenum and vanadium in a tool-steel base, creating an extremely strong metal
  • Safely operate in excess of 1,400°F temperatures
  • Each seat is individually cast using a process that, together with the special alloy, gives greater resistance to oxidation from fuel contaminants
  • Will not cause valve and valve-seat pocketing and recession
  • Seats have a rockwell C42 that rises to 50R/C during the first few hours of running time; made in the U.S.A.
