    Revolution Performance Monster Big Bore Cylinder Kit
    • Revolution Performance cylinders are aerospace-grade all-aluminum cylinders with nickel-silicon-carbide (NSC) electroplated bores
    • NO SLEEVING allows for larger bore sizes
    • NSC-plated cylinders have less friction for increased horsepower, lower engine temperatures and a longer lifespan
    • Monster big bore kits maximize cubic inches for increased power output with added durability and strength
    • Also require case boring, which is not recommended on OEM cases 95-earlier; some kits also require a 45/8" stroke crank
    • Includes pair of all-aluminum NSC-coated bore cylinders, custom forged pistons with high-tension rings specifically designed for NSC cylinders and a head/base gasket set
    • Upgraded cylinder studs and head bolts recommended
    • Replacement gasket sets available separately
    • Made in the U.S.A.

    NOTES:

    For replacement pistons and rings, see Revolution Performance Big Bore Piston Kits on page ???

     All kits require case-boring.
