With no need to rebalance flywheels, bore crankcases, or bore cylinders, this kit is about as easy as it gets. Consisting of the largest bore we feel can safely be used in a cylinder with a stock spigot diameter, this kit brings a new definition to the term 'big bore'. Forged coated pistons are compatible with stock or S&S Super Stock® 89cc heads Kit includes pistons, top end gasket kit, and S&S cylinders for 1999 - '06 Harley-Davidson® big twins. Wrinkle black finish.

Review:
I added this to a 2006 FLHTP. Still running stock cams, D&D Fatcat, Thundermax ECM, and H-D Stage 3 intake. The low end has considerable improvement and the top end is rediculous. It feels like ive gained about 13-15 HP. The real difference will be made when you port/polish the heads. This alone puts my Heritage to shame with it's 95" bore with 203 cams. All in all it the best money ive spent and the best bolt on performance. S&S still leads the way.
