One important factor to take into consideration to increase the engine’s rpm’s, is the valve train weight. The valve being the main component, the design has to be spot on for the weight reduction to allow higher rpm’s.

Ferrea’s latest design in this area is the Lightweight Hollow Stem Valves. Ferrea developed a proprietary manufacturing process that gun drills and micro polishes the bore of a valve stem. This proprietary process ensures greater structural integrity than any other hollow valve on the market today. The valve weight reduction is approximately 20 percent compared to a conventional stainless steel solid stem valves. The Ferrea Hollow Stem valves also feature  friction welded tips, radial grooves, avionics chrome plated stems, seat hardness up to 42HRc and Super  Flo designs to improve flow.
