The leading arm/trailing arm issue. It is a leading arm and Dexter only makes a trailing arm, so we called the Dexter dealer here in Phoenix and they called the Dexter installation guru's at the factory.
I spoke with an Engineering Guru at Dexter. I've come up with slightly different specs because I'm putting brakes
on and I have an American Boler
rather than a Scamp
Dexter makes a 3" rise bracket for snowmobile trailers that rarely gets shown in their specs. With the AP bracket kit for bolt on mounting that should give me a 3 1/4 inch rise to the frame. I'm crossing my fingers on this one but I should be able to mount this in the trailing arm configuration under the kitchen floor with little or no spacers. All that depends on how much of a bend gets put into the axle for camber.
I've opted to make the hub face 1/2 inch wider than my original, 1" wider than yours. The brake flange was looking a little too close for comfort to the inner fenders. My thought is if the tires
stick out too much, I can modify the outside walls of the trailer a lot easier than the inside.
(Dexter specs had a 1-1/2" recommended spacing to the outer wheel well, I thought that should also apply to the inner wheel well for our trailers)
The other thing I've done is to ask for the brackets to be offset by 1/2 " from center towards curbside. This should compensate for the frame / body discrepancy of 1" that was built into the trailer and equalize the position of the tires
in the wheel wells.
The dealer gets deliveries from Dexter every Tuesday normally they would expect it in next week. With the Memorial day holiday it might take 2 weeks for delivery. Retail pricing # 9 axle, EZ lube, e brakes
with park, AP mounts, high profile brackets and taxes comes to $482.59 CDN. That may differ a bit on pick up because the dealer did not have a price for the 7" brake with park and used the 10' price for the estimate.
I'll let you know how it works out. I've got the name of a local to do the install. Hopefully it works out that I can take pictures during the install. If not I've got befores, I can always take the afters later.
