Manufactured to the highest standards, these valves will take just about any reasonable abuse you throw at them.
- Undercut, back cut, and swirl polished for maximum flow and power at all valve lifts.
- One piece forged, high temperature, high nickel, stainless steel alloy SAE EV8. This material is stronger and less brittle than the competition’s cheaper 21-2N stainless at high temperatures- critical for forced induction applications.
- 3-stage heat treatment hardens tip and allows the valves to be super strong and super tough- if they do somehow hit the pistons they often bend rather than breaking, minimizing engine damage. DO NOT try that with the competition’s valves.
- CNC finished to strict tolerances for the ultimate in fitment and durability.
- Advanced nitride treatment process that both hardens the surface of the entire valve and reduces friction between the valve stem and guide. This means better high-RPM durability and better all-around efficiency. It also does not flake off like inferior chrome coatings used by the competition.
This item is a single exhaust valve, standard size.
