    Okay I'm going to preface this by saying; I do not care about how you feel on safety and rules and the government and so on and so forth. And if you want to be a genius and say something along the lines of "try the search button" well you're a bloody rocket scientist now aren't you.


    I want to put a flatbed dump on my truck. why? because of a few things ... A) its a work truck and a dump would be really helpful at times B)I'd like to use a leaf loader with it and move small amounts of mulch and not have to shovel it out all the time ...

    With that being said ... my trucks payload is about 3333LB ... thats not much once you add the bed and hoist ... however the rear axle is rated for 6000LB ... why in the hell can't I hold at least like 4500LB in the back of my truck? I don't see why that would be a problem the Axle can handle it ...

    IF YOU KNOW HOW TO FIX THIS PROBLEM answer this thread please with solutions not sarcastic answers from people who simply do not know but still want to be apart of this... THANK YOU

    are you looking to make your truck full dot compliant or just real world capable to run the extra weight ? A spring shop can help you with your suspension ,and your dealer might be able to help you figure out what kind of brakes if any your truck might need to haul the weight .If your trying to do this dot legall ,you would need to check with your dot about adjusting your pay-load capabilities ,which could be either very easy or not possible at all ,it really depends on what they will allow in your area .I have done this before ,but I dont even live in the same country as you so things are probably very different .

    I'm not sure how you increase capacity legally. GVWR is GVWR in the eyes of any enforcement. I've read of guys being able to adjust their GCWR for towing (not payload), but paying extra for this and is much dependent on the area you live. The one thing I've heard from many guys is to weigh your truck at a reputable truck scale place such as Cat Scales. They can give you your total trucks weight, front axle weight, and rear axle weight. Some are very surprised to see how much their trucks actually weigh and how much is on each axle. With the rear axle weight you can see where you are at. Now of course the axle is included in that weight and I'm not sure if the axle manufacturers count that # in their "6000lb" axle or if the axle could handle an additional 6000lbs?? Maybe the weakest part (bearings??) is rated to 6000lbs so that would include any weight on it, including the axle housing, etc... Again just guessing here.

    I'm sure you may have thought this already but could a bigger truck like a used 1 ton dually be better for you? That way you will probably have that 4500lb payload. I would just see how much it would cost to put the bed, hoist, and whatever other goodies on your current truck vs. selling the current and maybe finding a flatbed dump? If this isn't an option then thats ok.

    well I could do that but then I'd need a second truck to plow with because it's hard enough plowing residential with a srw ... thanks for the info I think I'm going to give a leaf spring shop a call and ask then what they know

    Despite your insistence that you "do not care about how you feel on safety and rules and the government and so on and so forth," you simply cannot separate that issue from this discussion just because you feel like it, nor can you legally increase your truck's payload.

    "Unless you're the proprietor of a certified coach builder, legally speaking there's no way to increase your truck's gross vehicle weight rating (GVWR)."

    Why you would choose to willingly and consciously open yourself to the distinct possibility of, at best, numerous tickets and heavy fines,and at worst, massive lawsuits, is beyond reason.

    Go buy a 1 ton or bigger to start with.

    I was trying to be nice but dbear is right. I don't plow but understand how a dually isn't the most residential friendly plower. Most spring shops will probably just give a round-a-bout answer as they are not going to tie themselves into a legal battle. They'd probably put on tractor trailer springs/airbags if you were willing to pay for it. Even when I bought a dump trailer and asked about GVWR's, GCWR's, DOT, etc.... they just said "We sell the trailers, you need to understand the laws." Basically saying "we are not tying ourselves into any liabitity." Hate to see you in an accident and be found negligent. Find out what your business needs and do the appropriate thing. Good luck!

    I found a solution (a leaf spring shop did not give me any run around at all) thanks for everyone's input

    I'd just put more leaf springs in the rear. Simple solution. You may want to also put stronger torsion bars up front or crank on them a bit...putting more leafs in the rear may give the truck a really nasty rake.

    $400 ... 1 spring on each side ... adds 1200LB that'd offset the aprox weight of the hoist and flatbed leaving me with the full +/- 3333lb which is perfect because I wouldn't be able to fit 3333lb worth of mulch, leaves, or grass clippings into the truck ...
