S&S Cycle 84-99 BT 96in 3-5/8in Big Bore Cylinder & Piston Kit For S&S SH96 Engines - Wrinkle Black - 91-7707

This 3-5/8" big bore kit may be used to replace the cylinders and pistons of an S&S V96 engine or a stock HD® Evolution® big twin engine that has been upgraded with an S&S 96" Hot Set Up Kit® with S&S® Super Stock® cylinder heads. This kit may also be used to upgrade an engine with an S&S 89" stock bore stroker kit to 96". Stock crankcases must be bored to accomodate the 3-5/8" bore cylinders, but the 4-5/8" stroker flywheel assembly does not need to be rebalanced. The kit includes S&S 3-5/8" bore cylinders, 3-5/8" bore forged domed Super Stock® pistons with rings and wristpins, head gaskets, base gaskets, exhcaust gaskets, and instructions. Compression is 10.1:1. The cylinders are nearly stock length, so stock length pushrods, and manifold may be used. Stock cases will need to be bored out to 3 5/8".
