2500 suburban

I am looking for opinions and/or experiences towing with a 2500 suburban. I have a eagle 314, probably #9000 loaded. I have been looking at a few but can't decide if I want a 6.0 with 4.10 or just get the 8.1. So far the 6.0-4.10 is harder to find.

I think you would be better off with the 6.0 and 4.10 set up.
That is the set up in my truck and i love it. I see alot of problems with the 8.1 engine and the parts are more expensive. ( auto technician)
The 6.0 is very dependable and just a little better on gas.

I may be wrong but I don't think the Yukon XL 2500 or the Suburban 2500 had the 4.10 option with the 6.0L. Even on the new builds only one transmission/engine option is available. When I check the past several years on Trailer Life Tow Guide they only list the stats for the 3.73 and that is the only tranny I could locate when shopping for mine.

I think he's talking about pre 2007. Late 90's/early 2000's may have offered different engines and gear ratios.

The 2001-2006 2500 had a choice of 6.0 with 3.73 or 4.10, and 8.1 with 3.73 and 4.10. The 2007+ only has the 6.0 with 3.73. The 2008+ had the 6sp transmission. The 2007 had the 4 sp.

The 8.1 will haul anything. My choice, if I can stay below 1000lb tongue weight would be a 2008+ with the 6.0, 6sp, and 3.73. It would get about 30% better fuel economy. But if you save $10k on the vehicle and afford extra fuel, then the 8.1 would be great.

I do not think there is much difference between the 6.0 and 8.1. And the 2001-2006 with the 6.0 and 3.73 was only rated for a trailer of 7900lbs.

I "believe" the GM 8.1L engines had the Allison tranny bolted to it, which would be a plus on my list.

If you do get a 2007-2013 3/4 ton burb, you can go to a RV hitch weld shop type of place and have them "beef up" the 1,000 lb receiver. I had Torklift in Kent, WA install a beef up on my receiver and it's now certified 1,400 w/WDH. I tow a jayco eagle with 1,400 lb tongue weight and 9,500 lb trailer and the burb tows it no problem. Powerful tow vehicle.

I found the earlier thread that raised concerns on the hitch quality for the 2001-2006 burbs while towing a 314bhs

I towed with a 2002 Suburban K2500 with an 8.1 ltr engine and 4.10 gears through all the US states. The trailer was 9K loaded.

I have 148,000 miles on it. I still use it to drive to work.

It has been a dependable and reliable car. I've had no engine issues. I replaced the AC at 80K, the U joints at 100K, and the brakes at 120K. Other than that, fluid changes.

I have been thoroughly pleased.

The Suburbans with 8.1 do not have an Allison transmission. They have a 4L85. Only the trucks with 8.1 had Allisons. The 4L85 is a great transmission.
