You obviously know more about trucks than I do...I do not know for a fact that the axles on a 2500 and 3500 are the same. I only posted the results from my trip to the scale and compared them to the ratings on my truck and the ratings published for a 2500.

I've been contributing to this forum since 2001, 11+ years before you joined, so if anybody is trolling it's you. The OP asked a question about weights and you're trying your best to turn this into an argument.

I believe that ratings are there for a reason, you obviously think they are concocted for political reasons have have no basis in fact. As my Dad used to say, "You're entitled to your opinion, no matter how wrong it may be."

There is one OEM rating that all of the anti-ratings advisors do believe in and that is the ICE "red line"

Haven't read anyone here recommend going over it...nor "I've been doing it for years with no problems"...or..."go for it"...

Unless you have a non computer controlled motor, redline pretty much does not mean a thing in today's motors. The computer shut fuel down if you reach too high of revs, so you can't over rev a motor generally speaking today.
Some like the Dmax I had would only let me get to around 3500 accelerating, but engine braking was 5000 or so.
My idi 7.3, and 6.5td diesel shut off fuel at 3000 and 3500 mechanically.
Not sure one could over rev a motor made in the last 20-25 years, be it has or diesel.

And yet aside from spring rate, the trucks are the same. Hence the helper springs. The other 2 items you’re claiming are just for effect, since 1 ton srw trucks are available with the same wheels and tires as 3/4 tons and shocks, well, 90% of factory shocks are less than stellar and they have no bearing on load carrying capacity.
Nice try though.

DUDE, don't you know the HIPS make all the difference???????

Bottom line for me...if someone asks for this kind of advice...they don't know enough about that situation to make up their own risk management decision(s) and will reference them to their OEM's specifications & manuals for THEIR vehicle & setup

The ratings are for warranty and registration purposes only. You can register a Tacoma to 14,000 lbs and load it up and be perfectly LEGAL, though I doubt it would move very far.

There used to be a larger mechanical difference between 3/4 and 1 ton trucks, but the manufacturers long ago realized that it is much cheaper and easier to put essenentially the same rolling chassis under either truck and change the spring pack and the sticker on the door to meet the DOT requirements for a class 2B truck.
The spring pack is easy to overcome, with helper springs, Timbrens or air bags.
The sticker can simply be ignored and your truck registered for whatever weights you are willing to pay.

My Ram has AAM 11.5" axles in the rear. They are rated to 12,000 lbs by AAM, derated to 7,000 lbs for the 3500 and 6,500 lbs for the 2500 with 18" rims, and 6,000 for the 2500 with 17" rims. Same axle.
The brakes, wheel studs, engine, transmission, rear differential, bumpers, bed, body, tires, radiator, etc are exactly the same. The frame is slightly different, just due to the shock mounts from the 2500 coil to the 3500 leaf. Ram rates the coils at 500 lbs lower than the leaf springs. If that 500 lbs worries someone, they can put bags or Timbrens to make up the difference.

The only reason that truck manufacturers make a 3/4 ton these days is to get into the class 2B market, which only allows a vehicle a max GVWR of 10,000 lbs. You can by a Ford F350 with a 10,000 lbs sticker, does that make it any less capable than an identical F350 with an 11,500 sticker?
