Hey guys I'm swapping out the lowers on my 08 FXDB and Im just wanting to make sure that before info further the new parts I have will be ok.

I purchased some black lowers from here and was told that they would work on my bike. I've also heard that they won't. So can anyone tell me based on the #s stamped on the parts below if swapping them out for each other will be a problem:

Existing left slider: G5C5-30-L SA-1
New left slider: G5C8-80-L SA-1

Existing right slider: G5C5-30-R SA-1
New right slider: G5C5-80-R SA-2

Also, I've got the fork tubes out of the trees but have not yet disassembled them down to the lowers, anyone got tips or suggestions?

 

Those aren't part numbers from HD. Probably the Showa part numbers. But just looking at the caliper mounts they don't seem the same distance apart.
Maybe this will help: http://www.shopronniesharleydavidson...partfinder.htm

 

Thanks, but I don't know if knowing the actual part #s is going to help as the new ones are from 2 different bikes I believe and different years, but that doesn't mean they aren't interchangeable.

For what it's worth, the seller said the new ones brake side is from a WG and the non brake side is a SG.

Anyone else got any idea if it will work? As far as I can tell they are identical other than cosmetically. The caliper mounts are the same.

I've already got the bike all torn up I don't want to get these put on and filled with fork oil only to find out the tire, brake, or fender won't mount properly.

 

I know its an older thread but im having the same issue. I bought lower chrome forks for my 2013 fxdc. Setting the old and new forks side by side all mounts and holes line up but my caliper barely fits on the fork and its rubbing on the outside pad to where the wheel barely spins and help advice would be appreciated thanks guys

 

Have any Pics?

Two possibilities for having 49mm Dyna sliders where the caliper-to-rotor alignment is "Off" when installing on your Mid-glide FXDC

1. If your fender mounts are the same ... you are incorrectly using a FXDWG Wideglide Left Slider
2. If your fender mounts are different ... you are incorrectly using a FXDF Fat Bob Left Slider

 

If everything else works, caliper spacers can pull that left caliper off of the rotor. They are just very thin 10mm washers basically. I've had to use them a couple of times over the years when I'm "customizing" stuff.

 

You would be moving the caliper in the wrong direction

there are ways to correct it, but NOT that way

i dont have any pics at the moment but i came across a wheel space kit i was thinking since its not off by much i could use a wheel spacer that was just a tad bit smaller but not sure how that would center the wheel up or if it would have any effect at all

 

If you can "Live with" the New wheel/tire "location" in relation to the fender/fork legs, then yes, you can INCREASE the Left spacer width to align the rotor within the caliper, but I would then SUBTRACT from the Right Spacer width whatever amount you added to the Left

.

 

Do you have any other ideas that i could try?
