749007 Valve Seat OD 1 945 ID 1 375 Th 440

AV&V valve seats are crafted from a highly alloyed material that balances machinability with extreme durability. Designed for Harley-Davidson engine builders, these seats are radiused to simplify the installation process into the cylinder head. The material is compatible with all fuel types and is engineered to dissipate heat rapidly, protecting the valvetrain from thermal fatigue. A unique characteristic of this alloy is its ability to work-harden during the engine's break-in period, providing superior resistance to valve seat recession and pounding. Whether performing a standard repair or a full performance build, AV&V provides the metallurgical consistency required for reliable engine operation. Sold each.
