over on RAWR occassionally

Keep in mind the F350 is SRW, not going to have a 9,000# axle rating, more like 6,100 to at most 7,000#.

Same axle as a DRW Ford so it IS rated at something over 9k, only the tires are holding it back from it's full potential.

That rear axle rating should be more like 9000 lbs I would think. The only limiting factor is the tires. I agree even the guys that use axle rating instead of GVWR usually don't go over their RAWR. In general a newer Ford F350 should be maxed out at about 3k lbs of pin weight.

This is the result of the GVWR being tighter to the total GAWR of the truck. Now days that is running between 90% to 95% of the total GAWR, so it is possible to exceed the GRAWR without exceeding the GVWR.

Never heard of exceeding RAWR without exceeding GVWR...and by 400# at that..per the OP, but hey, learn something new everyday...at my age, that's good, bummer is, I forget two old things:)

My RAWR is 9750#..so if I weighed my truck, ie, like checking pin weight with 5er hooked up, and I exceeded my rear axle weight by 400#, (weight being 10,150#, setting on the rear alxe,though GVWR is 14,000#), I'll be ok, because I'm only exceeding RAWR by 250# AND, if my Tires will handle 10,200#, I'd be ok anyway no matter what...yeah, I get it.....

..Guess we really don't need weight ratings on these trucks, it's more or less a joke anymore. I would think that if I exceeded my entire RAWR, no matter what the tires could handle that I'd be cutting into performance of the truck and subjecting the suspension to some untimely wear and tear, but again, maybe it really doesn't matter...load a truck to anything you want, nothing will happen and no matter you load the truck to, you really can't overload it...Dang, could have saved a pile of money by going with a loaded out 1500 with T/H package, I don't tow that much either, well right now I don't:)

You bought to much truck NCH, I'l give you a good deal to take it off your hands. Maybe even enough to get that HD 1500. ;)

Remember- the ratings are based on continuous use.
IMO- 400 pounds is no big deal. Other than keeping good tries on the truck and religiously checking the tire pressure before each haul (which should always be done anyhow)I would not give it a second thought- just run it.

You might want some airbags which will do nothing to the ratings of your truck but may enhance ride comfort when loaded-

For comparisons sake- My last truck logged tens of thousands of miles while 2k over the pin weight and 8k over the gcwr. Got 38k for that truck when I traded it in-

That truck ran just as good when I traded in as it did when I bought it.

I have a very good hitch on the back of the trailer and a Hitchhauler rated at 500 lbs. maybe I could put some stuff that I carry in front of the wheels in the storage area back on the Hitchhauler. If I'm thinking correctly I'd only half to shift around two hundred to two hundred fifty pounds to take off 400 lbs. of pin weight.

I have reweighed my truck and fifth wheel setup fully loaded to the max of what I could reasonably expect to carry. I am not over my GVWR but am over by 400 lbs. on my rear axle. What remedial action could I take or, if I am stubborn, what would the long term effect be on the rear axle? We are talking about twice a year being in this situation for a few thousand miles.

OK, I'm confused...He stated he's NOT over his GVWR (gross vehicle weight), but IS over his RAWR by 400#:h

Did anyone not catch this...If he is over his RAWR he's WAAYYY over his GVWR..unless he meant he wasn't over the trucks GCWR...but again, I get the impression that he IS over his trucks RAWR, but because his tires will handle more weight, he should be ok:h

yeah, I'm confused....If I have a 7000# rated rear axle and have tires that will cover 7500# of weight, the axle IS NOW the weak link. IF I hit a dip hard enough towing over my RAWR is there a chance something is going to happen with that much payload in the truck bed?

Guess there is no need to worry and I wonder about it and why the post?...only does it twice a year and been doing it for a few thousand miles so why post for an idea on how to fix it when there have been no issues....If you're exceeding your trucks RAWR, you need a bigger truck...even the people who ignore GVWR and go by RAWR, I don't think, would recommend one tow 400# over their RAWR.....but....the times, they are a changing....
