Ford F-350 axle ratings
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...

this may be a bit of the pot to the kettle, as I tow over GVWR, but I do respect axle ratings. I will agree that most 250/2500 have axle rating based on tires, but a 17,500# 5er on 250/2500 running gear is looking for trouble.
What if the 250/350 uses the same axle? It does, BTW.
Dodge does the same thing on the 2500/3500 same axle, different RAWR's. Dodge even used the same axle on a DRW for a 3rd RAWR on the same axle.
Not starting a war, just pointing out 250/2500 running gear is often identical to 350/3500 SRW running gear.

Yes, I do. Sorry, unfortunately, I can't tell you. Don't remember. Haven't driven the truck since October/November and won't for another few weeks.
Based on the math and OEM LT 245/75R17 tires it should be 2065 rpms at 75 in 6th with a locked tq converter. 5th would be 2650 rpms.
