EXHAUST VALVE SEAT OD 2.06 IN. ID 1.562 IN. Valve Seat Exhaust: OD 2.060" / ID 1.562" 1200 ccm (74 cui) 1340 ccm (80 cui)

Description

In an effort to develop valve seats that would meet exacting standards, KPMI tested and chemically separated several iron based valve seats. Eventually KPMI specified a combination of materials that gave them a seat with good uniform hardness and resistance to microwelding, wear, and recession. Casting a seat with this combination of alloys is not possible. Only with the latest in Powdered Metal Technology KPMI was able to blend these alloys, creating a high density seat with exceptional wear resistance, machinability, and thermal qualities. This material is compatible with all types of fuel blends, resists corrosion and burning, and is machinable with standard tooling. These seats have been thoroughly tested on the track and street, in high RPM multi-valve applications, high spring load V-twin applications, with leaded and unleaded gasoline, ethanol, methanol, and in naturally aspirated and forced induction applications. In each case they have performed flawlessly, making these the seats of choice for cylinder head builders everywhere.

• Seat material is compatible with leaded and unleaded fuels
• Offers excellent thermal characteristics
• Resists microwelding
• Leading edge with generous radius to ease installation
