Wish I could help but I don't know enough about these newer trucks. I know I'm fixing to build a new motor for my Burb as I don't think the TBI will be up for the task (nor will the 10 bolt rear either). If I was planning to pull more often than I am I'd probably go for the diesel swap. Hopefully someone can pipe in with some info though. That being said, I wouldn't be comfortable pulling a ton of weight with anything taller than a 3.42.
Need towing capability info and technical advice
Hello,
I am a new member looking for towing capability ratings on a 2014 GMC 1500. I currently own a 2004 Chev 2500HD with Duramax, great truck, no issues with towing my 6300# trailer. Bought the deisel thinking I would buy a much heavier 5th wheel, never did that.
Looking at new gasoline engine truck to tow the same 6300# trailer.
GM rates the 2014 1500 as follows...5.3 engine with 3:08 axle 6600# max towing. Now change to 3:42 axle and it changes to 9600# max towing.
This does not appear credible with an 11 % reduction in axle ratio to gain 45% more towing power with such a small change in gearing.
Another discrepancy is the 2013 1500-truck with 3:08 axle gearing is rated at over 7000# towing with a less powerful 5.3 engine.
At some point GM specs are not truthful.
I sure want to buy the right gearing, darn trucks are pretty expensive for us retired guys, don't want to make a bad choice.
Anyone who have any thoughts on this?
Also would like to really like to talk to someone in GM with real technical knowledge not just some fluff marketing weasel , anyone have contact info I could use?
Thanks for your help!
