Towing Capacity SLT 6.2 with 3.42 gears

[dlockwood26]

Has anybody seen the towing capacity for the SLT 6.2 with 3.42? I have seen somewhere the Denali with 6.2 is 11,500 to 12,000 lbs. I think the 5.3 with 3.42 is 9600.

Yeeeahhh I'm not going to tow 12,000 pounds with a 1/2 ton.

12000lbs is crazy for a half ton. There is no way the truck would be stable at high speeds.

10k with my 6.0 and 2500HD springs is a pain in the ass. Its a good thing that I only habe to do that once a year.

It is about 9500 lbs, same as the old style trucks depending on the model.

you wont get 12k on 3.42s guarenteed. To get to 12k your going to need 3.73 and Ive heard they might be putting 4.10s in it. I would not tow 12k in a half ton, I would tow anything 10k or less.

Thanks this is great info. Do you have access to the link for GMC with Denali?

I don't see the Denali or High Country listed yet? Maybe Thursday on release date?

It'll tow 12000 w/ max trailering package when equipped w/ 6.2 - it includes heavy duty rear end w/ different spindles and bearings, 3.73 differential, tranny cooler, etc

 

Why wouldn't you tow what it's rated for? I'd tow more tha 12k if I bought that- you kidding me? A heavy duty 6 speed fortified w/ a dedicated cooler, trailer brake, hill decent, 3.73 gears, 420hp/460tq??! Thing will piss all over 3/4 ton trucks from only 10 years ago rated for the same weight.

 

These trannies can take a shit ton of abuse, you should see some G8 and Camaro guys pushing 600rwhp w/ 100s of 1/4 mile passes.

 

Believe me- no way would GM rate the truck for that tow weight if it couldn't handle it.

The driveline isn't the problem. I think you would have a hard time controlling a load like that with a 1/2 ton truck.

[Chris]

Its the rear springs, frame, and brakes that keep it at a 12k rating

Sure, you would think that, but what I'm saying is that obviously is not the case. The 1500 weighs nearly 6,000 lbs in long bed crew cab configuration. The max trailering package includes heavier duty rear leafs, cooling, and shocks - it has all of what you're questioning and then some. Do you seriously think GM would risk lawsuits, massive quality/warranty claims, etc. by over-advertising the towing capacity of their trucks? If anything that rating is UNDERRATED - which is a common theme by GM across all its model ranges when it comes to ratings, and would be of particular importance in this application, because people often push the envelop a little on towing.

I tend to agree with you on a lot of this. A lot of people are under this old assumption that a 1/2ton is for 5-6k towing, which just simply isnt true. Todays 1/2 tons weigh 1000more lbs or even more than they did 10 years ago,and about the same size of old 3/4tons. The new trucks have bigger , rear, ends, suspensions, brakes, hitches, etc. I also beleive like anything the rated weight is probably less than what it really is. If you know how ratings work they usually build in a certain amount of leway then subtract it, look at elevator, it may say 2000lbs but more than likely its true capacity is more.

 

BUT BUT I will say this. Towing at capacity you must know all the facts, have a properly maintained truck and trailer, you always should even if your towing a 300lbs trailer, but at capacity there is less room for error.

 

Also 12k does not mean you can hook up 12k to it. You have to subtract your tongue weight which is on most loads is 400-600lbs. Then subtract the body weight of the people in the truck, and there gear. So say you got two 200lbs guys and 100lbs of gear(gear adds up quick). Now your true weight is actually more around10,800k what you can legally and safely hook to that truck..

A properly loaded trailer should carry 10 to 15% of its weight as tongue weight. The average holiday trailer is 600 to 1000 lbs tongue weight once you add batteries and propane. Assuming a 12,000 lb trailer means it would have 1200 to 1800 lb tongue weight. The current specs I can find only show max GVW at 7200lbs/payload 1800lbs (option C5Z) which is the limiting factor. At that payload rating you have to leave the wife and kids at home to get close to the max tow rating. Ford has an 8200lb GVW for their max tow package and that makes more sense than the NHT. I am not sure where you live but up here the highway police have a field day on nailing overweight 1/2 tons.

right exactly what I was getting at. But always look at your equipment. Different trailers mean different things. my boat and trailer weighs over 9k but tongue is 600lbs. My old 32 ft trailer that weighed 7200 dry the tongue weight was over 1000 think it was 1100lbs. Trailers matter as well, an RV has tow bars, e brakes and such which can make them more stable, but they also act like a sail which can make them wag and unstable. A boat usually is lower more aerodynamic and cuts through the air better.

 

Either way point being if your truck says 12k on plan on towing something that is probably 15% less than that number or even more.
