RAWR Question?

So help me 'cipher this....
Word on the rvnet street is that half tons are generally good for 3800-4800lbs RAWR depending on the setup (it's on the mighty door stickers anyway) and 3/4 tons are generally good for 6000-6500lbs rawr (from the super duper door sticker).

So was doin a little work last night to the Freedom Wagon. She's a 1986 GMC Sierra Classic K20 for those of you who arent' in the know.
With the mighty semi floating 14 bolt rear axle.

So I sees this little sticker...the infamous door sticker! (Not sure I've ever actually looked at one and studied it before, but with the littany of literature on the rvnet regarding the all powerful door sticker, I took a closer look!)

Well here it is. (Not the actual, my truck is blue, but it reads the very same as this image I pulled off the inner-webs.)



So's I get to thinkin, hmmm 6000lbs RAWR, bout the same as the rvnet weight cops say 3/4 tons are good for...cool!

But wait....there's more. This aint no strong as an Ox full floating heavy duty rear axle with a ring gear somewhere between 10.5" and 12" with big ole beefy double supported axle shafts.

Nooo, this is a puny little 9.5" ring gear, single row, semi floater axle....you know like today's half tons......the weak ones that are only supposed to be used for groceries, according to the weight cops.

So's I start researchin.
14bolt semi floater. 33 spline shafts, 1.37" diameter.
Hmm, look up the specs for my 2016 SilverAdo 1500 parked next to it....you know with the "weak" grocery getter 3800lb RAWR axle.
Whadaya know that 1/2 ton axle is 33 spline and 1.41" diameter!



Sooo, here's the question.
Did steel get weaker in the last 30 years?
Did mfgs get more regulated in the last 30 years?
OR
Did men become pansies in the last 30 years?

'Cause near as I can tell, my old axle is somehow rated for 3tons in a "8600gvw Camper Special" but essentially the same axle is rated 37% LESS in my "new" truck.

    I think you forgot to talk abut a tire upgrade!


    Yeah, that too. I always forget about that since I generally swap out tires with E rated within the first 5k miles
  • Pickups of all sizes are available in lots of configurations and are continually being upgraded. My 2016 F150 is better at towing than my 1991 F250 was and as far as I could find out it had the most power and the highest tow rating available that year. 10K on the bumper and 12.5k on a 5th wheel. It also had drum brakes on the rear axle.

    No no no! Logic make no sense. 3/4 ton good, half ton bad. 1 ton best!

    In all seriousness, this is what I have been saying for a long time. Today's half ton axles are much stronger than the 3/4 axles of decades ago that people had no hesitation loading up with 3k lbs. Not only that, but the breaking system is much better too. The main weak point of todays half tons versus 3/4 tons back then is the suspension which can be rectified with aftermarket add-ons even though the weight police will still get triggered over it. Improve the rear suspension of a half to where I am not dramatically nose high in the front making it unsafe to drive, and I would not hesitate to put the same loads people put in 3/4 back then.

    People are too caught up on the number on the door. Regardless of whether they are much stronger than yesterday's 3/4 tons, it can only haul groceries if it has a 1 on the door to many of the old timers because they are applying decades old logic to today's trucks.

  • Here's a pic of the subject at hand.



    Edit: Yes I know the rims are too narrow for the tires. Not my doing...It's gonna get some 35-12.50-20s on 20x11 steelies once she's all painted up and pretty.
