07 GMC Sierra Towing Question
I need some advice. I have a 2007 GMC Sierra 1500 Crew cab. It's the new body style, SLE1 package. It has a 4.8 liter and 3.42 rear axle ratio. The maximum trailer weight is 5400 lbs for my truck. Short of getting a new truck, what can I do to increase the towing capacity? Thanks for any advice.

Re: 07 GMC Sierra Towing Question
Yes you would have to recalibrate your speedo to accodimate the new gearing. Check with Hypertech to see if thier power programmer do this for you.

Re: 07 GMC Sierra Towing Question
OK. I'll check with Hypertech. Last question... If I have a certified dealer to the work, would it void my warranty?

Re: 07 GMC Sierra Towing Question
I'd check with the service manager at the dealership on that. If you call my work ask for Todd Nelson(Service Manager) or Tony Glenn(Fixed Ops Manager)

As Leevon said, the difference is in the gears.

Re: 07 GMC Sierra Towing Question
Thanks, all. The chart in the manual says if I re-gear from 3.42 to 4.10, max trailer weight goes from 5400 to 7400 lbs. My trailer weighs 5380. I'm not sure of the tongue weight. But since the weight is right on the limits of my truck's capabilities, I'm just exploring some options. I really appreciate all the great advice!

I would absolutely determine the tongque weight of your trailer. For a trailer that heavy, assuming your trailer has electric brakes, I would recommend using a brake controller (if not, a surge brake), weight distribution hitch and an anti-sway device, The gearing is not going to make a difference in tongue weight, braking capacity, or trailer sway, etc. Keep in mind, just because the truck can pull something doesn't necessarily mean the truck is able to control the load. I've seen too many people lose control of their trailers, and almost everytime, the out of control rig and trailer has damaged other vehicles around them. Be careful.

Re: 07 GMC Sierra Towing Question
have any of you noticed the Maximum Trailering Capacity 8900 lbs on the Gm web site for the 2012 1/2 ton truck? most 07 parts still fit the 2012's
dont get me wrong not saying some one with out "experience" should do this but any one who has pulled trailers and has the experience/skill and properly setup equipment would not have any problems pulling 8 to 10k with a 1/2 ton every now and then, now if you was always pulling 10k+ then you should upgrade to a HD truck but for just a few times a year not something I personally would do BTW..... new F150 (1/2 ton) rated 11,300 when properly equipped ![]() |

Re: 07 GMC Sierra Towing Question
That's more towing capacity than I would guess... it does kind of make my "see you in the morgue" comment sound a little extreme.

Re: 07 GMC Sierra Towing Question
Solution upgraded. ^^^^ That was a 2007 2500HD SLE Ext cab long box.
Just got a great deal on a 2011 2500HD SLT crew cab regular box. I kept the push bar and the tool box. Gonna miss that long box, though. It was nice loading up my Yamaha Grizzly against the toolbox and still being able to close the tailgate, while having my Dad's Polaris loaded in the RV Trailer... |

Re: 07 GMC Sierra Towing Question
I'm glad you decided to get something to safely pull that trailer.I've pulled campers and trailers for 14 years and saw some pull trailers that were very dangerous to me and them and everybody else that was close.
You will have the suspension to handle that with no problem. |

Re: 07 GMC Sierra Towing Question
Thanks, PAWS. Yeah, although I'm sure the 1500 could handle it, especially with a minor suspension upgrade and trailer brake controller, I also knew this would be at the limits of it's capabilities, so i didn't really want to chance it. Also, the 1500 is really momma's, and she didn't want me pulling the trailer with her truck. So when she said I can get a bigger truck... I had to hurry and get one before she changed her mind.

Re: 07 GMC Sierra Towing Question
this thread is better than the what can my bumper hitch hold... and the guys saying i tow 20000lbs with my bumper hitch...
a corvette has bigger horse and torque numbers so would you tow 5000 lbs with a vette? i pull my 7200 pound boat just fine with my z71 suburban.... thats why i bought it... but i had to get the one with a 4.10 gears... just remember... there is a proper way to tow and a persons ignorance of proper towing can kill someone...
