FERREA COMP. PLUS HOLLOW STEM VALVES - V-F1089P

One important factor to take into consideration to increase the engine’s rpm, is the valve train weight. Of course, being the valve a main component, the design has to be perfected to accomplish the weight reduction to allow higher rpm’s.

Ferrea’s latest contribution in this area is their 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 insures greater structural integrity than any hollow valve on the market today. This achieves a valve reduction in weight of approximately 20 percent compared to a conventional stainless steel solid stem valve. The valves also feature friction welded tips, radial grooves, avionics chrome plated stems, seat hardness up to 42HRc and Super Flo designs to improve flow.

Sold Individually.
Must use V-K10033 or V-K10067 valve stem locks for hollow stem valves.
