Description

Harley performance people that know will confirm that “You can’t beat cubic inches” S&S understand this and came up with the solution. First there is this Power Package. It will convert your Evolution Big Twin motor to 88CI (1475CC). This kit comes with .175″ shorter than stock S&S aluminum cylinders, flat top forged pistons with 1.200″ deck height, rings, wrist pins, circlips and gaskets. The cylinders are precision bored and honed. These kits are easy to install and ready to run, as no cylinder head modifications are required, only the crankcases must be bored to accept the kit. As these cylinders are shorter than stock these kits must be installed with adjustable pushrods and a shorter than stock manifold. Special pistons for use with S&S Super Stock heads are available separately.

S&S replacement piston kits for use in S&S 96CI V2, 113CI SuperSideWinder, and 124CI SuperSideWinder Plus engines, as well as many S&S and other aftermarket Stroker and Big Bore kits. Kits contain 2 forged pistons, piston rings, wrist pin and clips. Ring sets are also available separately.
