Good To Know
Q: Does this kit include a cylinder? A: No, this is a top end repair kit containing piston, rings, pin, and gaskets only; the cylinder must be in good condition or separately replaced.
Q: Can I use this kit for a rebuild after a seized piston? A: Yes, provided the cylinder bore is still within standard tolerance; if scored, honing or replating may be needed.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
