MONSTER BIG BORE KITS
  • Revolution™ aerospace-grade all-aluminum cylinders with nickel-silicon-carbide electroplated bores which means
  • NO SLEEVING; allows larger bore sizes and less friction for more horsepower, lower temps and a longer lifespan
  • Monster power in a package that’s tested, reliable and, most importantly, really big
  • Includes Wiseco forged pistons with rings (that are specifically designed for optimal compatibility with Revolution
  • Performance’s cylinders), wrist pins, circlips and high-performance head and base gaskets
  • Available in four finishes: natural silver, black, black with highlighted fins or granite (matches the engines of
  • Screamin’ Eagle models)
  • Replacement head and base gasket sets available separately
  • Made in the U.S.A.
  • NOTE: All kits require case-boring.
    NOTE: For replacement pistons and rings, see Monster Big Bore Piston Kits below.
