Frequently Asked Questions

Can I use this piston in a chrome or nikasil-lined cylinder?

Yes. Wiseco pistons are designed to work confidently in cast iron, chrome, nikasil, and boron composite cylinder compositions.

What makes Wiseco pistons different from stock?

Wiseco uses forged high silicon, low expansion aluminum that offers superior strength, reduced weight, and better heat transfer than cast stock pistons, extending engine life.

Is this a complete rebuild kit or just the pistons?
