Upgrade your Harley-Davidson Twin Cam engine with the KB Performance Piston Kit, designed for precision and durability. This kit features advanced skirt coating technology applied throughout the piston-to-wall clearance, ensuring a zero install clearance. During start-up, the coating abrades in to hone the perfect fit for your cylinder, resulting in optimal compression efficiency. The pistons include rings, pins, and clips, providing a comprehensive upgrade for your engine. Made in the USA, this kit combines quality construction with innovative features to improve performance and longevity.
KB Performance's hard anodized top ring groove prevents micro welding of the ring to the groove, maintaining a flat, smooth surface that enhances ring seal and reduces blow-by. The skirt coating minimizes piston rock, eliminating piston slap noise and promoting a quieter operation. Additionally, the hard anodized crown helps in heat deflection and offers resistance to corrosion from alcohol-based fuels. This piston kit is specifically designed for engines ranging from 96 to 103 inches, making it suitable for big bore builds with 85cc heads. Whether you're rebuilding for performance or reliability, this kit provides the essential components needed for a high-performance upgrade that withstands demanding conditions.
Built with precision and durability in mind, the KB909LCA.STD piston kit offers a seamless fit and efficient operation, ensuring your Harley engine performs at its best. The included components are engineered to work together, providing a balanced and reliable upgrade to your motor. Trust KB Performance's expertise in motorcycle engine components for your next project, and enjoy improved power, reduced noise, and enhanced engine life.
