117" kit for 99-17 Twin Cam 4-1/8" bore 4-3/8" stroke; 11.2:1cr (w/ 86cc heads); 10.3:1cr (dome pistons w/ 95cc heads)

Aerospace-grade all-aluminum cylinder with nickel-silicon-carbide (NSC) electroplated bore

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 will require case boring

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

Replacement gasket sets available separately

Upgraded cylinders studs and head bolts recommended

Made in the U.S.A.
