Fitment • 1999–'06 big twins

Features And Benefits • Installation of the 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 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 • Piston jets (p/n 31-2026) included • Maintains stock engine height
