BECAUSE WOMEN PREFER A MAN WITH

            A FEW EXTRA INCHES!!

 

106 CUBIC INCH BOLT-ON KITS FOR 96"/103" TWIN CAM

 

97 CUBIC INCH BOLT ON KITS FOR 88" TWIN CAM

 

Why settle when you can have more? The S&S 106 and 97 inch Twin Cam kit bolts right on with NO case boring required! And better yet, it includes PREMIUM components, starting with super-strong S&S aluminum cylinders with a thicker, more stable sleeve than any other cylinder on the market. That means better ring seal and MORE POWER! Forged S&S pistons, rings and gaskets (head, base and exhaust) round out this incredible kit. This kit will transform your Twin Cam into a powerful, exciting bike to ride, without the expense and down time of a complete tear-down to bore the cases. You paid a lot of money for your bike, donít settle for second best!

 

Note: The 106" kit will fit twin cooled motors.

Option to Make These Kits Even Better!

 

If your bike is over 2 years old or has more than 4,000 miles, you should consider upgrading to a full Cometic top end gasket kit. These kits include all rocker box, head, base, pushrod, intake and exhaust gaskets.

 

If you would like NRHS to gap your rings and pre-install your assembled pistons into pre-lubed cylinders you can also order that below.
