There’s nothing quite like the roar of a Big Twin, and with our complete Harley engines, you’ll get the power to back up the roar. S&S long block engines are machined to fit with your stock mounts and intake, but are built with high-performance heads, drive cams, oil pumps and crankcases for horsepower and torque unlike anything you’ve experienced. Low compression engines and high compression engines are available, and they come with a two-year warranty. You can also transfer over your existing fuel and ignition systems or order new ones to capitalize on your new capabilities.
If you prefer to rebuild your existing engine, we have an abundance of Harley engine parts made to the highest standards. Use Andrews grind cams, Kibblewhite exhaust valves, Drag Specialties connecting rods, S&S cylinder kits and more to build a custom motor that everyone will remember. Once you have all the big components, our bearings, bushings, guides and other accessories will keep them sealed and leak-free. And a motor bolt set contains all the socket-head bolts you’ll need to put your engine together.
With our Find Parts Fast tool, you won’t have to worry about ordering Harley engine components that aren’t an exact fit. We also have a number of engine tools such as piston ring compressors, rocker box wrenches, flywheel pullers and valve guide installs so you can do more in the comfort of your own garage.
