The KB Performance Piston Kit, part number KB662LCA.STD, is engineered to deliver optimal performance and durability for 96 to 103 cubic inch Twin Cam engines bored to 117 cubic inches. This kit features advanced skirt coating technology that is applied throughout the entire piston-to-wall clearance, ensuring a zero install clearance which then abrades in during startup to provide a perfect fit for each cylinder. This process promotes efficient piston movement and minimizes wear over time, enhancing engine longevity and reliability.
The pistons are equipped with a hard anodized top ring groove, which prevents micro welding of the ring to the groove, maintaining a flat, smooth surface that ensures superior ring sealing and reduces the risk of ring snag or piston slap. The skirt coating further eliminates piston rock, providing a tight seal and reducing unwanted noise, resulting in smoother engine operation. The hard anodized crown helps in heat deflection, aiding in effective heat dissipation during high-performance riding, while also offering resistance to corrosion from alcohol fuels.
This comprehensive kit includes pistons, rings, pins, and clips, offering everything needed for a complete upgrade or rebuild. Made in the USA, the KB662LCA.STD piston kit is designed to meet the demands of high-performance Harley-Davidson Twin Cam engines, providing a combination of innovative coating technology and precision craftsmanship for optimal engine performance and longevity.
