Ordering my Dexter Torflex axle

As promised here is a copy of my ProSpec from an engineer at Dexter. These aren't the exact specs I ordered but it gave me what I needed to know. The outside bracket dimension is self explanatory, hub face dimension will add length to your axle between the inside of the arms and the outside of the bracket (this where you figure in extra clearance for side walls, etc), and there are a bunch of other good dimensions on there like if you give the engineer your chosen tire and wheel size they will enter it to show the specs, which I figure is an estimate. I went with a short spindle, added .125" of extra clearance on each side, and will be keeping my overall trailer width just under 80" at the fenders.

Here is what I provided my vendor when ordering:

    Torflex #9
    Electric brakes
    EZ lube hub
    1/2" studs
    Capacity: 1500 lbs
    Bolt pattern: 5 on 4.5
    Hub face: 70.25"
    Outside bracket: 58"
    Low profile top mount brackets (STANDARD ORIENTATION)
    Spindle: Short
    Torflex start angle: 0 degrees
    195/65R15 tire on 15x6 wheel (with zero offset)

The only other confusing thing is the short or standard spindle. This does NOT change either the hub face or bracket dimensions, it changes the length between the inside of the arms. I know, I know, but this is not apparent because when you ask for the specs they automatically add more material between the inside of the arm and the outside of the bracket (I hope I'm explaining this right). The only way I figured it out was I got a ProSpec for the same axle dimensions, one with a standard spindle and one with a short spindle. The only difference on the two ProSpecs were the "inside of arms" dimension that changed from 59" to 60". Everything else was the same. When you look at the Torflex Application Information pdf, the "#9 overhang per side" minimums given for each of the two spindles are the actual dimensions from the hubface to inside of arm for one side of the axle. Confusing huh? You basically double it, 6.5" x 2 = 13" for the standard spindle (or 12" for short) and add this to the outside bracket dimensions to get the shortest possible hubface dimension. Dexter leaves .25" of minimum clearance between the inside of the arm and the bracket (there is another thread with a hand drawing to show this, but it has an error in the minimum clearance), but you can add to your hubface dimension to increase the clearance up to 10.9" per side. Again this was confusing because the engineer didn't decrease the hubface dimension when switching to the short spindle, he kept the hubface dimension the same which added .5" of extra clearance on each side between the inside of the arm and the bracket. Other than noticing the one change on the ProSpec, it would be easy to miss and is still confusing to wrap your brain around.

There is no price difference for the two spindles, but there is an extra price for the high profile bracket.

Here are all 5 pages of a Dexter ProSpec (I included the last two pages just to show the complete write up you will receive, although maybe I got page 4 because no matter how many times I told the engineer I wanted top mount, he kept it as side mount):
