Engine parts for Harley-Davidson and Indian V-twins: big bore and stroker kits, cams, heads, gaskets and seals, pistons, valve train parts and complete engines. Brands include S&S Cycle, James Gasket, Cometic, Drag Specialties and Kibblewhite.
Common questions
Can I install engine parts myself?
Gaskets and bolt-on parts suit an experienced home mechanic; internal engine work often needs specialty tools and a service manual.
What is a big bore kit?
A big bore kit increases cylinder diameter to raise displacement and power, usually with matching pistons and gaskets.
Will this part fit my bike?
Use Shop by Bike at the top of the page: pick your year, make and model and every product shows whether it fits. Category pages can also be filtered to your bike, so you only see parts listed for it.
