Wiseco Piston Kit Arctic Cat Thundercat 900 1993-1997 80.50mm SK1185

When you're pushing your Thundercat 900 to its limits, stock pistons become your limiting factor. The Wiseco SK1185 piston kit delivers the strength and thermal stability your engine needs to handle sustained high-rpm performance without detonation or ring blow-by. This is a complete top-end solution that takes the guesswork out of rebuilding—everything you need comes in one box.

Wiseco's high-silicone forged construction minimizes thermal expansion, which means tighter tolerances and more consistent ring seal across temperature swings. Whether you're running your Thundercat hard in the mountains or on the trail, these pistons maintain their integrity where cheaper alternatives fail.
