6 x 5 1/2 lug pattern
high profile reverse mounting bracket with reverse orientation
shock mount option
22 1/2 down start angle
33" wire leads
ez lube hubs
The only thing is ( I'll say ahead of time you warned me Andy) the mounting flange measurements are not exactly what I ordered, not exactly square and both axles flange distances are slightly different. The distance between the flanges varies. The differences vary from front of the mounting flange to rear by about 1/16" and the overall width is between 1/16 and 3/16" overall shorter than what I ordered.
The way I figure it the difference when split between both sides of the axle amounts to 1/32 to 3/32" and better a little shorter than too long. Hopefully I can pull the fishplate in flush when I torque it in and if worse comes to worse I can shim it. Before I start drilling and humping does anybody have a dissenting opinion or suggestions?
Your axle ratings should have been 3200 pounds each, or at least, 3000 pounds.
35 degrees starting angle, give the trailer more ground clearance.
More importantly, new 10 inch brakes, "perfectly" adjusted, are only good for 7000 pounds stopping power, but they don't stay that way, because owners do not adjust them periodically.
!2 inch brakes, similar to what your Airstream originally had, perfectly adjusted, have 10,400 pounds of stopping power. They don't stay that way either, but they will come far closer to getting the job done, any day of the week.
The big question is how do you stop your entire rig, "if" the tow vehicle brakes quit?
Certainly the 10" is very inadequate, and the 12 inch will get the job done.
I also don't understand why a manufacturer insists on 10 inch brakes, when the cost for the 10 inch and 12 inch, are the same.
To me, there is a great difference between "squeaking by" and getting the job done, when it comes to braking power.
Next is heat generated by the brakes when stopping.
Obviously, the larger the brake surface, the cooler they will be when stopping the same total rig weight.
I also believe that Dexter provides a "take it or leave it" design.
We provide equal to or better than the original axle design, and "never" inferior to it.
