S&S Cycle - 90-0098

Replace that worn out top end with the S&S 80" top end replacement kit. This kit contains S&S 3-1/2" bore high tensile cast iron cylinders, 3-1/2" bore forged pistons, S&S Super Stock cylinder heads, and all the gaskets and hardware needed to totally replace the top end of a tired 80" shovelhead engine. The high flowing ports and .590" lift capacity of the cylinder heads allow for improved performance and easy high lift camshaft intallation. The moderate 8:1 compression rato allows your engine run well on readily available premium pump gas.
