Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my piston? A: Check that the bore measures 42.00mm and the part number matches 1654CD. Ring sets are bore-specific, so verify the size before ordering.

Q: Do I need new rings when installing a new piston? A: New rings are generally fitted with a new piston for proper sealing and even wear. Old rings on a fresh piston can reduce compression and oil control.

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