About This Product
For Shovelhead owners looking for a massive boost in displacement, this S&S 93-inch big bore kit is the gold standard. Sold as a kit, it includes gloss black 3-5/8 inch big bore cylinders, forged pistons, rings, wrist pins, and all necessary gaskets and hardware. This kit is designed specifically for 1966 to 1984 Shovelhead models and must be used with 4-1/2 inch stroker flywheels. It delivers a manageable 8.2:1 compression ratio, ensuring great engine life and dependable street performance. Note that your crankcase spigots will require machining to accept these larger cylinders, making this a serious upgrade for a dedicated Shovelhead performance build.
Manufacturer part number: 91-9101.
