|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 in. and 107 in. 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 in. Bolt On Big Bore Kit: Our 107 in. Bolt On Big Bore Kit uses the same all aluminum plated 3.938 in. bore as the 98 in. kit, but with a different forged piston matched to fit the 4.375 in. 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 in. gasket kit upon request.
