Specs At A Glance

Good To Know

Q: Should rings be replaced when reusing a piston? A: Yes, new rings are normally fitted whenever a top end is rebuilt so the bore seals properly. Ring end gap should be checked before assembly.

Q: Is ring gap adjustment needed after installation? A: Ring end gap should be measured against the cylinder and set to the engine specification before final assembly. Confirm the gap for your exact bore and piston combination.

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