Product Description

The valves also feature friction welded tips, radial grooves, avionics chrome plated stems, seat hardness up to 42 HRc and super flo to improve flow design. Weight reduction in valve-train components is an important factor in increasing engine rpm’s. Generally, the valve is the heaviest component in the valve-train (in terms of inertial and fulcrum weight).

Reducing this weight without sacrificing structural integrity is a balance that is not easily accomplished. Ferrea Racing Components latest contribution in this area is their Lightweight Hollow Stem Valves. We 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
