Frequently Asked Questions

What compression ratio is this kit rated for?

8.5:1 compression ratio, suitable for stock or mildly modified EVO Flat Big Twin engines.

Do I need a gasket kit with this piston kit?

Yes — gasket kits are sold separately. You will need a head and base gasket set for proper sealing during installation.

What does the ArmorGlide coating do?

It reduces friction between the piston and cylinder wall, resulting in quieter operation and better scuff resistance during break-in.

Is this a Harley OEM piston?

No — Wiseco is a trusted aftermarket manufacturer used by Harley builders. This is not the factory Harley part but meets performance standards for EVO engines.

Will this fit a +.040 bore or larger?

No — this kit is engineered for +.020 overbore only. Different bore sizes require different piston kits.
