About This Product
Bring modern reliability to your vintage Big Twin with this KB Performance piston kit. Sold as a set in a +.010" oversize, these pistons are compatible with stock cylinders and heads, maintaining a factory-style 8.5:1 compression ratio. The T6 heat-treated 390 hypereutectic cast aluminum construction features 16% silicone, allowing for tight clearances and quiet operation. This kit fits 1941 to 1978 Harley-Davidson 74 cubic inch (1200cc) Knucklehead, Panhead, and Shovelhead models. Please note that the top compression ring requires additional clearance during assembly. This kit is an excellent choice for riders who want to preserve the character of their classic Harley while benefiting from advanced piston materials.
