It's a known fact that the Polaris 800 twin engine from 2008-current has some serious issues that if not now, will eventually need to be fixed. When that time comes, or if you want to ensure your engines durability today, install our new Engine Durability Kit!

Our engine durability kit was designed to last. Our kit features custom made Wiseco forged pistons. These new pistons are made from stronger alloy to reduce skirt collapse over time. The pistons come with new wrist pins and c-clips. We also use titanium nitride coted rings for faster break-in and longer life. The spacer plate is made from precision ground aluminum which we nickel plate. We also include a complete set of eight longer cylinder bolts and two longer dowel pins.

Due to the added case volume, you will see a 2-3 HP gain!
