S&S Cycle 320-0459

Stock bore stroker kits have always been an economical way to increase the displacement of your engine. Installation of this kit does not require any special machining, other than fitting the pistons. S&S stroker pistons, which are sold separately, are available in all standard oversizes. Stock 88" cylinders can be bored from 33⁄4" bore to 37⁄8" to accommodate the S&S pistons, or a pre-fit S&S cylinder and piston kit may be installed. Engines with factory 95" kits require piston fitting for the correct oversize only. Stock or S&S cylinder heads can be used. Fuel injected engines will require recalibration of the fuel injection system – the S&S VFI modules and closed loop sensor kits are highly recommended. Since stock cylinders are used the engine height remains stock.
