Good To Know

Q: How do I confirm this ring set fits my engine? A: Match the 78.00mm bore size and part number 7800YB to your piston and cylinder specifications before ordering. Bore size alone does not guarantee fitment across all applications.

Q: Is this an original equipment part? A: This is an aftermarket ring set for Wiseco applications, not an original brand product. Verify the cross-reference number against your existing components.

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