Towing

[snarkee]

maybe this has been covered, maybe not

 

in my book it says

 

2010 silverado

 

1500 crew 4x4 with 5.3 v8, heavy duty cooling and 3.42 = 9500lbs towing

1500 crew 4x4 with 6.2 v8, heavy duty cooling and 3.42 = 9400lbs towing

 

why does the 5.3 tow 100lbs more

[FarmerDave]

Just going to go out on a limb and say it's because that engine configuration weighs less, so 100 lb lighter truck = 100lb more towing based on gross weight. Clearly the 6.2 can pull more, but not legally.

6.2L uses the same block, different bore, if anything it would be lighter.

 

To answer the original question:

 

I don't know.

in 2009 it was 9500 lbs. for the 5.3, 9300 lbs. for the 6.0/6.2 for the CCSB 4X4 3.42 ratio

 

add the NHT Max Trailering Package and the story changes though...

There are a number of factors considered for GCWR, including power, cooling, braking, etc. Maybe the 6.2 gets hotter on long pulls, or maybe the rear axle just weighs that much extra. Apparently, both meet the spec power requirements at these loads.

well comparing the 5.3 to the 6.2 is like an apple to an orange.....the 6.2 is a beast

Tow to your comfort level and forget about the limits in the book..........

 

If you think 9400lbs is toooo much don't pull that much.... If you think it will handle more than they getttter done....

 

My 2001 2500 4wd 6.0l 3.73 G80..... With my goose neck I have hauled in the neighborhood of 24k to 28k............. It does it without any problems.... Does not deplete the suspension....... Truck/Trailer seem very stable.. I have NO CLUE what the book says for my truck.... I kept adding weight every trip I made with the trailer till I found it to be tooo much and backed off a couple thousand lbs..

 

Oh yeah, I run LT series tires with the max # of ply's I can get/find...

 

Just my 2 cents....

trailer is only 7000lbs.....i was just curious thats all

[desrtrat]

a lot also has to due with factory tire/rim combo. not all factory tires have the same weight rating, even at the the same load rating. are they say 16" 17" 18" 20" steel or aluminum rims, or say, 265 or 275 285. tires

now go with after market tires/rims can change all of the numbers. say a 275-55-20 has a load rating of 2800 lbs max @ 40 psi and you change to 275-45-20 the max may be only 2400 lbs max @ 40 psi. you just changed your GCWR.. when i changed out my factory stock 275-55-20 with another tire manufacture same size i increased my GCWR by 550 lbs. due to different rating by the tire co.

point is.. when buying/replacing tires check the weight rating of the tire, not just the load rating(C D E)

 

hope this can help

Do they have the same transmission ??
