Valve - Exhaust - 1.630" - Oversize Racing Profile - Evolution Big Twin
Features
- One-piece stainless-steel, stellite-tipped valve is fortified by a special nitrided process with .002" depth and .0002" surface buildup to improve wear properties and reduce friction
- This process provides resistance to corrosion; wears superior to hard chromium and electrolysis nickel-plating
- Lightweight with profiles that provide excellent flow characteristics
- Compatible with leaded and unleaded fuels and can be run in cast iron- and bronze-type guides at close tolerances for maximum oil control and heat dissipation
- Made in the USA
