Wiseco Piston Kit for Harley-Davidson Evolution 1340cc 1984-1999 K0215P3

If you're running an Evolution 1340cc and serious about sustained power delivery, your pistons need to handle the thermal and mechanical stress of high-RPM operation. Wiseco's K0215P3 kit delivers the durability and precision engineering that separates reliable performance builds from failures. Built in the USA with forged crowns and proprietary coatings, this is the piston upgrade that won't compromise your engine's longevity or output.

The force-fed pin oiling system keeps your piston pins lubricated under extreme conditions, while the ArmorGlide® skirt coating reduces friction and scuffing—critical factors when you're pushing displacement limits or running aggressive valve events. The pressure seal groove design minimizes power loss by preventing ring flutter, ensuring every combustion cycle translates to usable horsepower.
