Tow Rating
 

Need to confirm tow rating for a 2013 Chevrolet Suburban 1/2 ton 4x4 LTZ with Z82 RPO is 8000 lbs.

Look on the drivers door

Tow rating is not on the driver's door. All that the drivers door tag gives you is axle ratings and max payload/gross vehicle weight.

Please point out where on these stickers is my tow rating?

Z82 has nothing to do with how much you can pull. It's driven by your 2wd/4wd, axle ratio and whether or not you have the heavy-duty cooling system.

Code KNP is the heavy-duty cooling package.
Code GU6 is the 3.42, don't know what the code is for the 3.08.

4wd reduces all ratings by 100 lbs
Towing ratings:
3.42, cooling - 8100 lbs
3.42, no cooling - 5600 lbs
3.08, no cooling - 5100 lbs

That being said, I'd strongly recommend you do NOT pull anything near 8000 lbs with a half-ton Burb, even if you do have the 3.42 and the cooling package. You'll overload your rear axle long before you get anywhere near 8000 lbs. I pulled a 7000-lb trailer with my half-ton Burb and broke stuff, while on vacation, multiple times.

GVWR 8600 lbs. Top left corner

My 1/2 ton is rated at 6700? I agree

GVWR is gross vehicle weight rating. It means the maximum amount of weight you can put on the four tires of your truck. It has NOTHING to do with trailer weight. GVWR simply tells
you, with a little math, how much payload your truck can handle. My GVWR is 8600 lbs, and since the other sticker says my payload is 2088 lbs, that tells me that the curb weight of my Suburban is 8600-2088=6512 lbs.

GCWR is Gross Combined Weight Rating, which would be the maximum weight of truck and trailer, but GCWR isn't on the stickers. ;)

So the sticker on your door has 6700 lbs on it? Show me.

I would check your owners manual. Or google trailer life towing guides for useful info. You will need to know things like axle ratio, 4x2, 4x4, towing package, etc. It has a little guide at the top.

That's what my source link pointed to, and where I got all the weights listed. ;-)

LOL sorry, I didn't see the source until now, my bad. :)
