- Premium valve seats for applications using steel valves
- A specific combination of alloys allowed a creation of a high density, iron-based valve seat with uniform hardness, exceptional thermal qualities and high resistance to wear and recession caused by microwelding
- Only by using the latest developments in powdered metal technology were we able to blend these alloys to give a seat material with the qualities required for today's engines
- These seats have been tested on the track and street in high-rpm applications with leaded, unleaded, and oxygenated fuel, as well as methanol, ethanol, nitrous, and forced induction applications
- Made in the U.S.A.
- Verify size before ordering.
