High Performance Titanium/Inconel Coated Racing Exhaust Valve
This high performance racing valve is coated with a blend of Titanium and Iconel, to make a one of the strongest and most heat-resistant valves ever produced for performance engineering. The lightweight strength of titanium is well known, but Iconel is part of a family of super-metals known for being extremely oxidation, corrosion and heat resistant. When blended with titanium, it becomes well suited for service in environments which are subject to pressure and heat extremes - such as racing motorcycle engines.
Note; If you have questions about what valve springs should be used or if lash caps are to be used, please contact us.
Oversized Valves
Our oversized valves (OS) are flow tested for maximum performance.
Oversized valves can also be used to rejuvenate sunken valve seats while correcting valve geometry.
The OS valve features relocated keeper locations to accommodate hi-lift racing cams and springs. This saves additional machining expense.
NOTE: Always be sure to check piston clearance before installing oversize valves
