Legal vs recommend tow ratings for 8.1L Burb/Yukon XL

[dkad260]

Thanks for the info, I guess in a worst-case scenario I could prove the vehicle's specs.

I know it might sound like I'm overthinking it, just wondering if the GVWR remained the same on both 3:73 & 4:10 models, as well as axle rating...this would be on the door sticker. My thought process is if I get the 3:73 and decide to swap gears, would the info stamped on the vehicle still be the same. Not like we're going from a short bed to a long bed, SWB to LWB, but in this particular case, the vehicle pretty much remains the same except for a 10% gearing change. Hope I don't sound like I'm overly obsessing over a few pounds...lol.

How does the 8.1 Burb/Yukon do with about 10K behind it using the 3:73?

Thanks again for all the replies.

That pretty much mimicked the conversations I had, I forgot to also include the tires in my earlier post....thanks for adding that.

The tow rating on my SWB Envoy 4.2 w/ 4:10 is 6200 lbs, my registration came with a 11K GCWR. I had it weighed with a full tank of fuel, no persons aboard and was 4720 lbs. Not much room for persons and cargo.

But the numbers that count are the 11K on the registration, tires, and axle weights on the door sticker. I was able to raise the GCWR to 11,500 for a safe margin at time of renewal.

I had a Trailblazer with the 4.2. Read the fine print on your Envoy. I bet that 6200# rating is only for use with a load-leveling hitch. Else, it’s around 4000# with 400# on the tongue. My boat slightly exceeded that and towing any distance just didn’t feel safe. Airbag helper springs would have helped, but braking was insufficient.

That's correct. I haven't tried to pull 6200 lbs but quite a few short distance 5K loads on a tandem axle landscape trailer. Loaded correctly the Envoy balanced nicely but you definitely knew it was back there, generally kept under 4K lbs though.

Sounds like the bottom line is if you tow 15/20 miles a few times a year but the burb is better for trips you’ve made the decision easier. Either rig will pull your boat but the other 98% of its life fits you better than the truck. I’m sure your trailer has great brakes and if you need a WD hitch to feel a little better about tongue weight do that. Good luck.

This is what I would think as well. We have all gone over here or there on a need to get it done basis. But doing it right is The only way to go. The law probably wouldn't know the difference but safety of family comes first.

Just don't do this. And yes the cop's were all over him.

There's 1/2 ton trucks all over Minnesota pulling 10,000 lbs . Your thinking way over kill . 4:10 on even 335 hp can pull amazing amount weight . If your going to think it's going to pass in accident . They will always find fault where ever they want to.
Long as loads right on trailer and it's got good brakes. It all comes to the nut behind the wheel.
Ooo and how much money you want to waste on a rig .[emoji41][emoji106]
