About This Product
This KB Performance piston kit is designed for 1200cc Big Twin engines requiring a +.030" oversize. Sold as a set, these pistons are compatible with stock heads and cylinders, delivering a reliable 8.5:1 compression ratio. They are crafted from T6 heat-treated 390 hypereutectic cast aluminum with 16% silicone, which enables the engine to run with tight clearances and minimal piston noise. This kit fits 1941 to 1978 Harley-Davidson 74 cubic inch (1200cc) Knucklehead, Panhead, and Shovelhead models. Be sure to provide the required additional clearance for the top compression ring during installation. These pistons provide a high-quality, durable solution for refreshing the top end of your vintage Knuckle, Pan, or Shovel.
