Need Some Tree Width and Angle Info

After two days of searching I need some confirmation of the numbers I came up with. I am wanting to put Wide Glide or Fat Bob trees on my 2008 Low Rider. I want to retain my stock tree rake which I think is 2 degrees. So what I think is true is 08 Low Rider mid trees are 2 degree rake, Fat Bob wide trees are 0 degree rake, Wide Glide trees are 2 degree rake, and the wide trees are 2 inches wider than mid trees. Can anyone confirm if all this is true or add correct information. Thanks for the help.

Low Rider trees do not have rake as far as I know. The LR shares the same frame as the WG which gives it more rake in the frame, 32 degrees as opposed to all other Dynas at 28 degrees.
HD has never listed the LR as being raked out like it does the WG which does have 2 degrees in the trees giving it a total of 34 degrees prior to 06, in 06 they gave the WG 34 degrees in the frame with 2 in the trees for a total of 36.

2006 and up:

Low Rider has a 29* frame neck with 1 1/2* triple trees

Fat Bob has a 29* frame neck with 0* triple trees

Wide Glide has a 34* frame neck with 2* triple trees

Mid Glide to Wide Glide/Fat Bob width = 1 1/2" wider

Thanks WS6 Formula and 8541hog,

That's exactly what I needed. Especially the data that the Wide Glide frame is where it gets most of it's rake. I will only gain 1/2 of a degree of rake mounting Wide Glide trees on my Low Rider.
WS6 your bike is done superbly, I like the custom nature of it still using OEM parts. That takes a lot of research and trials.

Thanks. This in information I've been curious about. So if I installed LR trees on my FXDC I would gain 2 degrees of rake. It looks like a straight across swap, right? I like that idea.....anyone have any for sale?

I think you would gain 1 1/2 degrees. Look at WS6formula's post above. Either way 1 1/2 or 2 degrees, you will gain enough to see.

did you have to space your fender or did you buy a wide glide fender

From a hardware store: 3/4" spacers and 3/4" longer stainless Allen head bolts for mounting the fender, and stainless washers for shimming (.040" for the caliper & .090" for the rotor) to center the caliper over the rotor.

Use other existing hardware from your bike (axle nut and washer, triple clamp pinch bolts, head bearings nuts and washer, fender nuts, forks, etc.).

I bought the parts from Zanotti's back in June of 06.

Here are the Harley Davidson part numbers and Zanotti prices:
P/N 46700-06 Upper Triple Clamp.....$ 65.75
P/N 46386-06 Lower Triple Clamp....$139.83
P/N 40923-06 Front Axle..................$ 28.39
P/N 40926-06 RH/FRT Spacer.............$ 4.58
P/N 40927-06 LH/FRT Spacer.............$ 4.58
Total..$243.13

Update: 4/3/08
Axle spacers above are also available in a chrome tapered version P/N 41410-06 Chrome Tapered Front Wheel Spacer Kit $23.51

Original Wide Glide tire replaced with only 7,300 miles on it (Not much tread left). Replaced it with a Avon Venom AM41 90/90-21, widest tire (3.70") I could find that will fit the Wide Glide Profile rim.

I know this is an old thread, but I came across it looking for similar information and figured I'd add what a 2008 American Iron article said about the FBob fork/tree angle(s).
"The neck has a rake of 29 degrees, a fork angle of 28 degrees, and a trail of 4.92". Since the trees actually derake the forks by one degree, the Bob has the smallest fork angle of any Dyna."
