2003 GMC 1500HD CC towing capability


Recommended Posts

Posted

I'm trying to find out what my truck is capable of towing. My owner's manual doesn't even list the 1500HD crew cab when talking about towing. I've searched online and found anywhere from 6000 lbs to 10000 lbs. Where can I find the true number? Can I find a number for off the axle too? I want to get a 5th wheel and want to know what my options are. I have the suspension air bags.

Thanks for any help!

I have a 06 1500HD which is basically the same truck. If you have the 3.73 rear end gears GT4 code in your glove box your truck is rated for 8600lbs. If you have the 4.10 rear end gears GT5 code in your glove box your truck is rated for 10,500lbs.

Sorry dude, I looked around but I found nothing specifically for your year truck so I'd have to go with THABULL on this one. Maybe PM one of the GM Customer Service people and they can find something for you.

 

EDIT: By chance did they consider yours a 2500 LD? I only ask because I found...

Pg. 4-78 talks about a 2500LD.

 

Curious, very curious as to why they don't cover the 1500HD in their own book.
