Do the math, first !!
can any one tell me for sure if a 70 tooth final drive from an 06 dyna, 6 speed will fit properly and line up ok on an 07 Ultra, and replace the 66 tooth to get some gear back ( to 2.95.) the 2.79 is just too tall for me. i am only looking for small gain 150 - 200 rpm @ 70 mph i've done the math, it's what i want, i just don't know if it will fit and work, ( belt change also ) a 32 tooth comp. gear would also do it but no one makes it, only a 30 ( too much ).that i know of. any ideas would be welcome. thanks much THEDRIVER
