Does axle size matter when swapping out lowers? I have a 2007 with 1" axle. I think the new LowRiders are 25mm correct?

Monster,
What engine mods did you do to get 129hp/147tq?
This is for an '11 street bob right? Why wouldn't the legs match? They're mirror images of each other? If you mean because the new LR comes with black legs, that right leg is available in the standard clear coated finish.

I put a 124" in her last year

I don't think the components themselves are any different, just the brake lines themselves since the upper and lower both run back to the box and don't just connect to each other like a standard brake setup. There's abs dual brake lines on magnum sheildings website. The fat bob has been out for a while so I'm sure between the fat bob and new low rider, one of them has got to be available with abs. I don't see an issue with it, only extra cost should be the more expensive brake line kits, not much more money, certainly no reason to buy a new bike just for dual disk. Remember when your shopping for parts needed you need to be shopping for a new low rider or fat bob, not your street bob. LR right leg, everything else can come from either fat bob or LR.

Yea I believe you would need to swap the axle and wheel bearings. Good opportunity to switch to timkin bearings instead of the Harley stuff. May need a new bearing spacer tube and outer spacers too but I'm not sure. Just cross reference your 07 and an 08- later street bob and see what components have different part numbers

I am about to do this swap when I get my new LR wheel and leg back from powder coat. I'll put together a list of parts that I got to do the swap and post a build thread. It'll be a couple weeks tho

I read on another thread that the 14+ LR sliders were slightly different than the previous years. If I'm buying new, then I'd rather just buy a new '11 FXDF right side and be done with it. If I can find a used FXDF, then all the better OR a used matching set off of whatever that will fit my '11 Street Bob.

I'm looking at doing cams in the next year... I'll ride the 96" with cams till I blow the motor, then was looking to upgrade to a 110" or better.

As mentioned, FXDF sliders have their fender mount bosses in a different location with different hole spacing. People hack their way through that, but how's your OCD going to deal with that?

In addition you really wouldn't want to then add a Left-side FXDF slider after the right-side because it's a wide-glide slider with caliper mounts moved more inboard than your mid-glide sliders. But people hack through that when putting them on mid-glides by milling the calipers themselves.

You might want to go with one of the other solutions

Really good points. I would think the new LR leg would be the cheapest/ easiest way, if the finish is somehow different then powder coat both legs... What do I know... I got the unpainted leg and it looked identical to what my legs looked like before I powder coated them. If he means the right LR leg is different other then just the finish I don't see how, I'm pretty sure the LR uses the same exact left leg that's on his bike now....

Yes, the introduction of the Dual disc on a Mid-glide in 2014 really was long overdue and offered a great solution for single disc owners.

I'm not sure what difference he was referring to unless it was slight casting differences at the caliper mounting area. I think they changed in 2013.

Maybe you can see the differences below

All 49mm sliders will accept 1" or 25mm axles. Each has the same respective O.D. where the axle mates with the sliders. Try to stay with 1" if you can...better bearings IMO.

As I mentioned, I read it on another one of the dual disc threads here on the forum... and now I can't even find the damn thread to point y'all to for referencing where I got that info...

I found a new '11 FXDF right side slider for $140 off of Boardtracker Harley Online (which is what came up when I searched for Kutter Harley as someone mentioned above) and went with it. $140 + free shipping... sounded good to me.

I'm also aware of the difference in the fender mounting from a '11 FXDB to a '11 FXDF and so long as the jerry rigging to make it fit is as straight forward as others have made it out to be, then my OCD should be fine with it. If not, then I'll wind up replacing the right side and fender to make it match, but I can deal with it until I scrape together more cash to deal with looks issues on the bike. Everything right now is fit/function oriented.
