Frequently Asked Questions

What compression ratio does this piston deliver?

10:1 compression. Higher compression increases power but requires fuel with appropriate octane rating.

Is the gasket kit included?

No — gasket kits are sold separately. Order the matching gasket set for your engine displacement.

What is ArmorGlide coating?

A proprietary skirt coating that reduces friction between the piston and cylinder wall, lowering operating temperature and improving scuff resistance.

Does this require honing the cylinders?

Yes — this is a +.010 oversized piston. Cylinders must be bored and honed to the corresponding .010-over size for proper fit.

Will this fit my Twin Cam or Milwaukee-Eight engine?

No — this kit is for EVO Big Twin 1340cc engines only. Milwaukee-Eight and Twin Cam engines require different piston kits.
