Description
When you’re rebuilding a 2-cycle top end, piston quality directly determines how long your engine will survive at full throttle. The Wiseco SK1398 kit eliminates guesswork—you get OEM-spec pistons, rings, pins, and gaskets engineered specifically for your Polaris 800 RMK, so you can focus on performance instead of premature failures. High-silicone forged aluminum means these pistons handle sustained heat without excessive expansion, keeping ring seal tight and combustion efficient across the entire RPM range.
