Do you know what is driving the reduction in towing ability, my 04 Tahoe, 3:73, 5.3 – 190 hp, 4 speed auto has a maximum trailer rating of 7400 lbs, the 07-LTZ I have ordered is reduced to 6700 lbs even though the 5.3 is now capable of producing 320 hp, and brakes have been improved. Tire size does not seam to be the issue as the stock 245/70/17 and the optional 265/55/20 have approximately the same diameter as the stock 04 tires.

Sorry, but I'm not up to speed on the reduced towing. It may be simply a matter of weight. It also could be that the LTZ with its premium ride suspension has some limiting factors.
 
The HP is only a component. Torque is more important. And there are considerations on the ability of the cooling system, transmission, axle ratio's etc. in handling the extra loads. You'll note that if you go with a 4.10 rear axle ratio, the towing cap goes up. Also, the 5.7 ltr engine produces more of its power at a lower RPM than the smaller 5.3 ltr engine.
 
In the older Suburbans, the greatest towing capacity came with a rear leaf spring suspension, and those ugly steel wheels. For good measure, they offered the 454 big block or diesel.
 
Maybe someone else on this post knows the inside scoop.

If I am correct, both the 04, and the 07 both have the 5.3, I do believe that the 5.7 was ever available in the new style.

You are correct. The 5.7 was retired prior to '01. I'm mostly familiar with the 6.0 ltr ('01 Denali), and the 5.7 in the '96 Suburban, so this didn't cross my mind.
 
I would have to guess that its a matter of the newer platform, meaning frame, suspension, curb-weight, cooling, that is made them revise their ratings.

I believe this is part of the double seals used to help make the ride quieter. It also keeps rain and mud from entering the area where the latch is, and on the lower sill. Other than getting some wax on it, and having to put armour-all on it, it doesn't seem that big a deal.
 
My wife's BMW has a similar double seal on the rear doors, but they do a better job of hiding it.

My 2002 TrailBlazer had the same type of exposed weatherstrip and never seemed to be a problem. Hope my '07 LTZ proves out as well.

I'm guessing it has to do with the extra curb weight. The new design gained at least 500lbs. IF the GCVWR (Gross Combined Vehicle Weight Rating) didn't change and the curb weight increased then the tow rating goes down.
 
The decreased towing capacity is interesting. Heck, the current Explorer is rated to tow more.
 
Lots of things effect tow ratings. HP & torque probably have the lowest effect on what the ratings actually are. The suspension, chassis, brakes, and transmission etc. are far more important in determining what a vehicle can safely tow. Look at 3/4 and 1 ton trucks. The diesel option does not increase tow ratings over the biggest gas engine.

jnrz -
I have my new performance exhaust on order with Zoomersexhaust (supposed to be shipped 5/26) - I will be able to let you know how it sounds (along with a link to an mpeg hopefully) shortly after that.
