J2807 has arrived for 2015 at GM

[dznf0g]

Thought some of you might be interested in the J2807 tow ratings for GM for the 1/2 tons. Several configurations changed by 3 - 400 pounds, but Max Tow remains the same.

2015 Silverado 1500 Will Tow up to 12,000 Pounds, Based on SAE J2807

So now its Toyota and GM that are SAE certified. Hopefully, Ford and Ram will follow suit.

I think everybody is in for 2015.....at least that's the rumor.

BTW, it's not a certification. It is a set parameters that the SAE came up with, and manufacturers voluntarily participate in.

Its a good thing as it allows customers to objectively compare tow rating of vehicles from different manufacturers.

Yes, but it will also cause more confusion to the "am I overloaded question".
It is a performance based test which does not reflect the loading CAPABILITIES of the vehicle. In other words, you're not going to be able to make sense out of the GCWR, GAWRs, GVWR if you try to match them up to the J2807 trailer rating.

It is a good marketing spec tool for the technically challenged shopper.

Same thought as Rich. Will be interested to see what they begin showing for load capacity of the vehicle. In the past it has generally been with just a driver and fuel for a base vehicle. Most of the time that isn't close to reality.

[dznf0g]

My understanding is all the load specs will remain unchanged in their engineering process calculations and will still be available for us gear head math geeks. J2807 only affects published trailer specs.

What I read was:
2 passengers weighing 150 lbs ea
70 lbs of hitch equipment. (Hitch head ball dist bars
Article did not specify payload ratings. This was on GMs media web site.

This is all good information, but just as before, the average buyer (and salesman) will assume that you can certainly tow that 12,000 lb trailer with this new 6.2L truck without regard to exceeding the gvwr and rawr of the truck.

I don't understand your point or question??????? The 150lb people and and 70 lb hitch are the SAE numbers that all manufacturers use for the tests. Payload numbers are not part of J2807, strictly "what is the max trailer weight a truck can operate under and still meet all the acceleration, braking, etc. parameters of the test".
That's why I call it a performance spec and not a true "capability" spec.

No question Dan, We consumers still need to know our p's and q's. The GVWR, GAWR, GCWR,etc. numbers are still important numbers to spec a truck properly.

[subfan1]

The point was that now they are using two people weighing 150 lbs ea and 70lbs for hitch equipment. Post 7 indicated that generally manufactures used only one person in a base model to determine tow ratings.
I had not read about the 70lb hitch equipment rating until now.

[dznf0g]

That's true, Sub. However, that one person was raised to 190,iirc a number of years ago. The gvwr etc specs are DOT regulated from a fluids and occupant perspective.
