Proudly Made In The U.S.A.

Revolution Performance Big Bore Kits are the most powerful, technologically advanced American V-Twin Big Bore Kits in the world! Our state-of-the-art all-aluminum cylinders made in Wisconsin increase both reliability and horsepower. Comparing our nickel-silicon carbide bores to cast iron cylinders, Revolution Performance big bore kits dissipate heat faster, are lighter in weight, and are 10x more wear resistant! Since our cylinders and premium forged piston are made from the same materials, the engine components heat and expand at the same rate, allowing for tighter tolerances and more power!

Bolt-On Big Bore Kits

Revolution Performance bolt-on big bore kits are exactly that, a bolt-on application for your engine. Bolt-on big bore kits are the most reliable way to increase power and torque on your engine. Each kit comes with our state of the art all aluminum NSC plated cylinders which last longer and run cooler than the OEM cylinders. The cylinders are matched with a premium forged piston and a Cometic head gasket kit.

No case boring or additional modifications/upgrades needed. However, additional modifications/upgrades will help make this bolt-on big bore kit a complete package.
