Cylinder Kit - 139" - Black with Highlighted Fins - 107" M8
Features
- Aerospace-grade all-aluminum cylinder with nickel-silicon-carbide (NSC) electroplated bore
- NSC-plated cylinders have less friction for increased horsepower, lower engine temperatures and a longer lifespan
- 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
- Made in the USA
- Will require case boring, which is not recommended on OEM cases '95 and earlier; some kits will require a 4.625" stroke crank as noted.
