Frequently Asked Questions

What's included in this kit?

The piston and rings. Gasket kits are sold separately and must be ordered to complete a rebuild.

Do I need a tuner with these pistons?

The 10:1 compression ratio may require fuel mapping depending on your fuel octane and ignition system. Consult your tuner before installation.

What does ArmorGlide coating do?

It reduces friction between the piston skirt and cylinder wall, lowering operating temperature and improving scuff resistance during break-in.

Is the piston pin oiling sufficient for street riding?

Yes — force-fed pin oiling delivers constant lubrication during operation for both street and performance use.
