Good To Know

Q: Does this include the valve itself? A: No, this listing covers the valve seat sleeve only, so order valves and retainers separately if your rebuild needs them.

Q: Can I install this without machining the head? A: Seat sleeve installation typically requires pressing and seat cutting by a qualified machinist to ensure proper valve sealing and clearance.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
