KIBBLEWHITE Nitrided Valve — Head Ø 1.935 in, Stem Ø 0.309 in, Length 3.620 in, Tulip angle 23° – 70-85 Sportster

Meet the nitrided valve — a one-piece, stellite-tipped component fortified by a specialized nitriding treatment for improved wear resistance and reduced friction. ⚙️

The nitriding develops a .002" hardened depth and a .0002" surface buildup that extends service life and minimizes galling.

Designs focus on light weight and optimized profiles to deliver excellent flow characteristics and consistent performance.

• Superior corrosion resistance and wear characteristics compared with hard chromium and electroplated nickel.
• Compatible with both leaded and unleaded fuels and engineered to run in cast-iron or bronze guides for tight oil control and heat dissipation.
• Manufactured in the USA for strict quality control.
