2005 suburban 2500 6.0 3.73 gear? anyone towed with one?

I have a 2007 Suburban 2500 with 4.10's. Tow beast really. The motor is made to rev so you will be at 3500 rpm's up grades. I'd make sure to get the 4.10's unless you get a 2008 model. The 2008 and newer has the 6 speed selectable tranny.

I think mine is rated at 9900 lbs. would recommend it heartily. Great vehicle.

2004 6. 0.3.73 3/4 burb checking. 4 Captions delete rear seat and tow a 5,000lb tt around the 7 to 16% grades of north east pa..

Yes, 8.1L with 4.10 rear axle.

Burbman- does your suburban have the 6.0 or 8.1?
I would have to guess the 8.1 being the tow capacity so high..
Krobbe- What kind of MPGS are you getting with your 8.1 suburban with the 3.73?
Thanks

At 60 to 65 I get 7-8 against a headwind and 9-10 with the wind. Avg 8.5.
It's not my daily driver. It only gets driven to tow or on some summer weekends.

Edit: Just found out the mass air flow sensor was bad/dirty. May see improved mileage.

My TT weights are close to yours. My Suburban 2500 8.1L 3.73 tows it without effort. If you're set on the 6.0L, try to get it with a 4.10. But the 4.10 axle ratio won't make up for displacement.

GM rates the towing capacity with that engine and the 4.10 gears 25% higher than with 3.73 gears. It does make a difference.

5.3L->6.0L a bit more power, a bit worse first gear, same FE for that era.

1500 Tahoe -> 2500 Burb will be very much more stable.

If you don't use this much non towing, try to find an 8.1L.

Dave-how heavy was your travel trailer you towed?
Were you able to keep up to speed on the highway to typical highway speed?
Also, did you feel like the 2500 suburban was in control? When I tow with my 1500 Tahoe it feels like my #6500 travel trailer is in control and not my tow vehicle, which is scary.
Thanks in advance

My trailer at that time was around 6500 loaded. I did keep up to highway speeds, and don't recall issues of feeling pushed around by the trailer. Of course, some of that can be having a properly set up WD hitch and anti sway system, but the longer wheelbase on the Burb compared to the Tahoe would be noticeable as well.

Jbres, the Suburban will handle that trailer fine. Big difference in going to the 2500 series from the 1500 series Suburban and Tahoe is the suspension and brakes. 2500's get rear leaf springs and front torsion bars, same as the HD pickups, while the 1500s have coil springs and are set for comfort more so that towing a load, which is why you feel like the trailer is controlling the Tahoe today. The 2500's also get massive disc brakes at each corner.

When you say tow rating is "only" 7700 lbs that's a more a function of drive train....my Sub is rated at 12,000 lbs towing and has the same frame and suspension as the one you are looking at.

The 6.0L is no powerhouse though....better than the 5.3 but not as strong as the big block or diesel. As I said for your camper you will be fine, but if you have plans to get a bigger/heavier TT in the future, you will be upgrading the truck again.
