96" 3 5/8" Sidewinder Big Bore Cylinder and Piston Kit for 1984-'99 Big Twins with Stock Cylinder Heads -Wrinkle Black Finish

This 3-5/8" big bore kit may be used to replace the cylinders and pistons of an engine that has been upgraded with an S&S 96" Hot Set Up Kit® with 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 flat topped pistons with rings and wristpins, head gaskets, base gaskets, exhcaust gaskets, and instructions.

Compression is 9.75:1.

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".
 **TECH NOTE: YOU WILL NEED TO BORE OUT THE STOCK HEADS WHEN INSTALLING THIS KIT**

**S&S recommends that this kit be installed by a skilled technician.**
