Raising GVWR

A lift axle will allow roughly 7k more in freight I think.....after accounting for the extra weight of the new hardware.

So yes. I am in the same boat. I need another axle behind my tandems.....just for those certain loads...

 

Ratings come from either the original equipment manufacturer or the body upfitter and can be modified with a little work and the proper paperwork process. The paperwork required varies from state to state and depends upon which state your truck is currently titled in.

Example, here in Pennsylvania we need to document all the work done to increase GVWR with receipts and pictures, have a rebuilt vehicle inspection form completed (MV-426) and submit to PennDOT for a new title and registration upgrade. The hardest part in PA is getting the reconstructed vehicle inspection as only a handful of garages are licensed for this particular inspection.

I would use a company that does truck upfits regularly, maybe a place that installs dump bodies or wrecker bodies as they are very familiar with the incomplete and modified vehicle process, can get you the right paperwork and issue the yellow sticker for your door with the new GVWR and axle weights.

 

I'm putting on my pretend lawyer hat.

Can the truck do it? Sure. But the issue is if something happens and you wind up in an accident. If you are running over the GVWR of the truck, those lawyers you see up on the signs standing on the hood of a truck will be standing on the hood of yours.

If your loads are that heavy get a larger truck.

 

Yes you can, no you don't have to do much other than add an axle to it.

BUT because you are doing expedited freight (I'm assuming), you need to understand by the time you dump all that money into the truck, you could have bought another one that is already to go.

Oh and if you have a cat C7, don't bother trying to get any more power out of it.

 

Even more to the real world is "routine roadside inspections" and inspection stations. They always look at the GVWR on the door post, so you can register it for more, the tax office is happy to take your money, but you cannot exceed the GVWR as depicted on the door post plate loaded going down the road no matter if the registration says more. That's what you will have to get upgraded before you haul something that will cause that weight to be exceeded. That's my experience anyway.....
