About This Product
When it is time to freshen up your top end, this KB Performance 1200cc piston kit is a top-tier choice for 1941 to 1978 74-inch Knucklehead, Panhead, and Shovelhead engines. These are +.060 inch oversized pistons designed to work with stock cylinders and heads, maintaining a reliable 8.5:1 compression ratio. Sold as a set, these T6 heat-treated 390 hypereutectic cast pistons feature a 16% silicone content, allowing for tighter clearances and quieter operation. Each piston weighs 370 grams with a 97-gram pin. Note that the top compression ring will require additional clearance during installation. These are built for longevity and performance in classic Big Twins.
Manufacturer part number: KB263060.
