The conventional Milwaukee-Eight cylinder use an iron liner cast into an aluminum cylinder. Although extremely cheap to produce, cast iron liners have a lot of disadvantages compared to modern cylinder construction. Revolution Performance Big Bore Kits use an all-aluminum cylinder design that utilizes a proprietary nickel silicon carbide cylinder plating process. The plating forms an extremely hard barrier on the cylinder bore. This plating has exceptional wear resistant with excellent oil retention and an extremely low coefficient of friction. The Revolution Performance cylinder and piston are the same material, so they expand at the same rate when exposed to heat. This means tighter, more precise tolerances can be used and the cylinder will run up to 40 degrees cooler. The result is cylinders that are lighter, more durable, and make more power than a cast iron cylinder. Much more power.

The 124" Bolt-On Big Bore Kit requires no other engine modifications to install but can benefit from our other services like our Velocity CNC Cylinder Head Package.
