Our most reliable big bore kits are also our most easy to assemble! Our bolt-on big bore kits are the best and most reliable way to get instant access to increased horsepower and torque. How much, you ask? Each of our bolt–on big bore kits increases your power and torque gain by at least 25–30% on average, just by bolting in our cylinders and pistons!

Each kit comes with a set of our aerospace grade all aluminum nickel–silicon carbide plated bore cylinders as well as our custom forged Revolution piston kits, and let’s not forget the high performance head and base gasket set! For the quickest access to high performance gain, the 98” and 107” bolt-on big bore kits definitely give the best bang for the buck!

Each kit comes with the option of three stock colors: Black with Highlighted (silver) fin edges, Natural/Silver, and All Black. For further specs and information, see the descriptions for each kit below.

107” Bolt–On Big Bore Kit: Our 107” Bolt–On Big Bore Kit uses the same all aluminum plated 3.938” bore as the 98” kit, but with a different forged piston matched to fit the 4.375” stroke of the 2007 and later twin cam models. Although only one piston is offered with this application, we can lower the 10.5:1 compression with a .045” gasket kit upon request.
