After months of research i settled on the Frankenstein kit for my 2004 electraglide classic.That kit is the best i could find .the diff.is a dana 30 with 9 in.ford axles.it's what is referred to as a live axle.spider gears.I must say this kit is great.And when they say you cant use your $500 fl exhaust they are wrong.all you need from them is the s pipes and hangers.after shortening my fl mufflers.5 inches.and cutting and rewelding the s pipes.you just shortened the exhaust by 14 in.and all the welds are covered by exhaust heat shields.pipes stick out 3 inches behind their fl fenders.and they look mean.and there is no cutting on the head pipes.the mufflers they sell with the exhaust kit are whyatt Gatling mufflers which sound like drag pipes on a shovel.
All in all the Frankie kit is Made overkill.and if anyone gets this kit the 7 degree trees are a must.i rode a independent suspension kit and they are good for bumps but that is all.take some fast curves and you feel like your comming off.another note if you install a conversion a good set of low end torque cams such as andrew ev26 will restore the power you just lost.hope this helps anyone on deciding on what they are looking for.as for towing you cant use the hitch they sell if it's a Fl. It wont clear the fender.fab one up yourself and use their mounting points.who pulls a trailer with a sportster anyway.ill post some pics on how the exhaust was done and hitch soon as i get. The hitch completed.
