are the case bore dimensions on the new style S&S 4.125 cylinders the same as...

[No Cents]

I've got a set of cases that were bored for the new style S&S 4.125 cylinders using a 4 3/8" crank. Are the new style S&S 4.125 cylinders for the 07-up 124"er with the 4 5/8" crank the same case bore measurements?
Just curious.

I would say they probably are, the year of the case shouldn't mean anything to the cylinder spigot diameter.  but you might look up the base gasket part number at the S&S site, that may tell you.

Yes, I have the S&S cylinders with the 4 1/8" pistons for the 124" big bore for my 117"

I looked up that part#...and that is the old style barrels. I'm wanting the newer style that mimic the factory cylinders.

I have the S&S mid year update catalog, they're only listing the 106 inch cylinders with the new style part number. They may not be making the other cylinders like that yet.   

Maybe call them.

Thanks guys...I found it.  I googled my 117 cylinders part# and poof...all the new style S&S cylinders part #'s page appeared.
Ohio HD...these are the same cylinders used on the new S&S 124" for the 07-up models.

I did get it, thanks. So the 910-0255 that FLTR2008TRIKE gave us looks to be a good number for the updated cylinders too. Good deal.

Yep...when I googled his part# it showed the old round barrels. When I found this page it showed why I seen the old cylinders...but his part# was good for the new cylinders with the conversion numbers.
Thanks FLTR2008TRIKE!

I have a set of SE cases bored for Axtell 4.125 cylinders, is there any difference in the case boring dimensions. Will the S&S cylinders bolt straight in??
