Specs At A Glance

Good To Know

Q: How do I know this ring set fits my piston? A: Match the 74.80mm bore and the 2945TDW part number against your piston specification before ordering, since ring sets are bore-specific.

Q: Can I install this ring set on a used piston? A: It is intended for the matching piston and bore, so check ring groove condition and end gap during assembly to confirm a proper seal.

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