Zylinderkopfteile

The Super Alloy Engine valves represent the highest level of sophistication in valve technology. These valves are designed to handle the extreme heat requirements and punishment of today’s Nitro Fuels, Supercharged, Turbocharged, Nitrous Oxide, and Marine race motors.

The 6000 Series Competition Valves are designed to provide excellent reliability in an environment of high spring pressures and roller cams, at a budget price. They have higher fatigue resistance and tensile strengths than our competitor’s best offerings.

To manufacture the valves we use our exclusive two-step slow forging process using EV8 stainless steel on both intake and exhaust valves.We provide a special heat-treatment and stress relieving process, along with hard chrome stems and friction-welded hard tips. We finish with a swirl polished head. The valves feature flow improvements to deliver the power needed for today’s sophisticated racing engines.
