We purchased a new Excel Winslow 31IKE last October. It has a 17,500# GVWR. Our F-250 diesel pulls it just fine but a trip to the scale yesterday shows we are 240# over our RAWR of 6100#. I can not find a dually, Ford, GM or Ram, anywhere in our area so am considering a SRW F-350. Problem is those available have axle ratios of 3.31 or 3.55. Not Ideal nor either the GVWR of 11,500#. Those of you who have a Ford F-350 SRW 2013-2014 model year, what is your rear axle rating and with what axle gear ratio?
Thanks

Go look at your tires and see what they are rated for.
Ford uses the same axle in F-250's and SRW F-350's, rated at 9,750lbs by itself.
If you'd are comfortable ignoring the door sticker knowing that the axle itself is rated for more than the sticker then you can go off of tire load capacity. This is not uncommon, and not illegal. DOT cares about registered weight and tire capacity.
This will show you that the brakes and other important parts are the same from F-250 to F-350 SRW, just a different door sticker.
