Specs At A Glance

Good To Know

Q: How do I confirm these rings fit my piston? A: Check that your Wiseco piston carries the 3839XH number and measure the bore at 97.50mm. The set is piston-specific, so both details must match.

Q: Do these rings need gapping before install? A: Verify end gap and side clearance against the piston maker's spec during assembly. Some applications call for file-fitting the end gap.

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