How many of you run over the front GAWR?

    Just wondering. And if so, how is your suspension holding up, and how does it affect driving performance?

    I got a non-snow plow prep package 250 that I am thinking of either mounting a Boss 8'2" V, or a Western 8' 5" MVP + on. The MVP would put it over, the Boss would not. How do you guys handle it?

    You could put a 9'2" Boss V on a Ford F250. Even one with a diesel. A gas engine is much lighter and will handle it even better.

    I'm not saying I run overloaded, but my Dodge with a diesel carries my plow fine..

    I was thinking of adding a leaf to all 4 corners come spring and bringing it up to 350 class anyway.

    I dont know about on a Ford but on a Dodge the front suspensions are exactly the same. I know, that doesn't help you. Let's see if some Ford guys chime in about the differences in front suspension between an f250 and f350.........

    It is my understanding that a 250 and 350 can be speced the same way.

    My 350 has a lighter FAWR than my 250 does.

    The newer F250 & F350 have the same rating in the front. Not sure what year this began.

    Well I have a Chevy 2001 2500HD w/ 8.1 with a utility bed and this weights 8000 #'s. I put 37-- 50# bags of ice melt in the bed and hang a Snow X 575 on it. Then I put a Meyer 7-6 foot blade on the front. I have not done the math.

    Going over the GAWR of your vehicle is not a good idea, while it may hold up fairly well during most driving it could also fail at the worst possible time.

    The reason for this is GAWR is calculated to take into account the transfer of weight that occurs when you get into an emergency braking situation. With any vehicle weight will transfer to the front axle as you brake, the harder you brake the more weight is transferred, so what the GAWR says is we can safely put X lbs on this axle and still absorb all the weight transfer (Y lbs) that could occur in braking (which means X + Y is what the axle is actually capable of holding). What this means is that for every day driving around with no hard braking you'll probably be fine (since while your vehicle is siting it can probably hold more than the listed GAWR), but if you ever have to brake in an emergency situation (like needing to go from 50mph to 0mph in a few seconds) your risking a catastrophic failure of some front end component (whatever the weakest link is in your particular vehicle).

    I looked into this when i was buying a second truck, it's the reason i didn't go with the truck i originally wanted because the blade i wanted would have put it over the GAWR.

    PS GAWR is also based on the weakest component of the axle/suspension so adding leafs ect might not change the GAWR if that's not what the weakest component was.

    not a good idea to go over...... may be fine but on the other hand could be very bad.

    From what I've seen, the difference between snow plow prep and non-snow plow prep is 400 lbs on the GAWR. 4800 vs. 5200.

    My old plow weighed around 719 lbs. with the Ultramount and Ultra to Uni adapter.

    The new MVP is around 880 lbs. steel, 847 lbs. poly which I am leaning towards.

    It can't throw me that far over I think.

    You cant over load a Ford's front end, especially with leaf springs for suspension....Your talking only 130 lbs....You'll be fine

    It would be easier to ask who is NOT over their FAWR.



    Can you share your math how you came to this conclusion?

    The Western might have its weight farther out than the Boss. Weight is not the only factor. Distance from the axle also plays into it. Edit Boss shows 770 for the 8'2" Western 880 for the 8'5"

    I used the plow match selectors on each company's website.

    Better yet, how many even know what their FAWR or actual FAW is.

    Ford's F250 and F350 axles are good for 6000lbs, the limiting factor on FAWR is the spring. They use the same axle in an F250 gasser as an F350 Diesel. Upgrade the springs to x-codes, add-a-leaf, or air bags, and you're good to go. Fords chew through ball joints regardless, plows generally speed them up a little though...

    I'm gonna see how the plow hangs, then I might go from there, and possibly do air bags on all 4 corners.
