Frequently Asked Questions

What's included in the kit?

Complete piston assembly with forged crown, precision rings, and all hardware. Gasket kits are sold separately.

What does +.010 mean?

The piston is oversized by .010 inch, requiring a corresponding bore hone to match. Standard .030 and .060 oversizes are also available.

Will this fit my Evo Big Twin?

Yes — this part is engineered for EVO Flat Big Twin 1340cc engines. Confirm your engine displacement and generation before ordering.

Does ArmorGlide coating make a difference?

Yes. The ArmorGlide skirt coating reduces friction, lowers operating temperature, quiets the engine, and improves scuff resistance compared to uncoated pistons.
