The WISECO Black Edition Piston Kit is engineered with specific ring configurations to optimize engine performance and oil management. The assembly features a premium compression ring designed for an ultimate ring seal, paired with a Napier second ring that utilizes a taper face and underhook to improve oil control. Additionally, the kit incorporates a 3mm oil ring design that provides higher tension and enhanced oil control within the cylinder.
Surface treatments are applied to reduce mechanical stress and wear. The piston features an Armor X coating to mitigate wear, while the skirt utilizes an ArmorGlide coating to lower friction, ensure quieter operation, and improve scuff resistance. This piston kit is compatible with both OEM and Screamin' Eagle cylinder heads.
