About This Product
For vintage Big Twin engines needing a significant overbore, this KB Performance piston kit is sold as a set in a +.080" oversize. These pistons are designed to work with stock cylinders and heads while maintaining an 8.5:1 compression ratio. Made from T6 heat-treated 390 hypereutectic cast aluminum with 16% silicone, they allow for tight clearances and quiet operation. This kit fits 1941 to 1978 Harley-Davidson 74 cubic inch (1200cc) Knucklehead, Panhead, and Shovelhead models. Note that the top compression ring requires additional clearance for proper installation. This kit is a robust option for saving older cylinders and ensuring your classic engine runs smoothly for years to come.
Manufacturer part number: KB263080.
