Frequently Asked Questions

What's included in this kit?

Piston, rings, pin, and clips. Gasket kits are sold separately and must be ordered as a standalone item.

Is this a stock or high-compression piston?

This is a 10:1 dome piston — higher compression than stock. Verify your engine's current bore size to ensure +.030 overbore is correct for your build.

Does ArmorGlide coating really reduce wear?

Yes. The ArmorGlide skirt coating lowers friction between the piston and cylinder wall, reducing scuff risk during break-in and extending ring life.

Do I need a new gasket set for my rebuild?

Yes — order a gasket kit separately. Reusing old gaskets risks leaks after boring and honing.

Is this made in the USA?

Yes. Wiseco Tracker pistons are forged and assembled in the United States.
