Specs At A Glance

Good To Know

Q: How do I know this ring set fits my engine? A: Confirm your piston bore is 85.00mm and that the ring set part number matches your piston before ordering. Ring sets are matched to specific piston and bore combinations.

Q: Should rings be replaced with a new piston? A: Replacing rings alongside a new or freshly honed piston helps ensure proper seating and sealing. Reusing worn rings on a new bore can lead to poor compression.

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