Valve Seat Inserts for Iron Head Sportster (KPMI)
These Valve Seat Inserts are specially sized for Harley-Davidson Iron Head Sportster. They are designed to effectively dissipate heat for consistent valve sealing. Each seat insert has a radiused edge for easy installation and they will harden during engine break-in. Both sizes are .315" Thick.
AV&V Valve Seat Inserts are being discontinued by Goodson so they are limited to stock on hand. They are being replaced by Kibblewhite Valve Seat Inserts.
