2500 crewcab with 350 heavy towing

poot · Aug 14, 2015

I have a 97 2500 with 3.73, 4l80e, and haul corn and hay with gooseneck trailers. I've scaled 35000 loaded before and never had any issues. Just don't try to clime hills to quickly.

Hook it up, if it pulls it, run it. Ive pulled more with less.

These old trucks can haul basically anything. These things are lasting the test of time. ;-)

I agree and for your situation, even worst case scenario shouldn't cost more than $2000 to fix. New engine or transmission are relatively cheap compared to buying a newer truck outright. These trucks are built tough, even if something does go out you should be able to limp to an auto shop and not have to be towed.

and I agree 4.56's would make a huge improvement and not work that engine and trans nearly as hard.

My 3500 has a 350 but is a 4spd. I've hauled a lot but it definity is slow up hill. Still with 200k I would want it serviced before any 300 mile trips.

Remember on these, the 98-02 older body style work vans used Vortec 5700 (5.7) engines and had 4L80E's with 3:73 full floating rear ends. I've driven a number of them. They are plenty fine for doing some towing, probably wouldn't go towing other trucks around on a daily basis but for most boats/reasonably sized campers I'd think they'd be fine. Depends how you drive it and how often/far it's being used for towing.

Yeah, to be totally honest, -almost- every single 8 lug 2500 I've ever owned or worked on, 4.10's all day long. The one exception I can recall is a '91 RCLB 350/4L80E that had 3.73's, was a bare bones Cheyenne with a flatbed. On the other hand, all the 6 lug 2500's I see tend to be 3.73's.

adding to the thread revival, my 96 burb 454 has 3.73s also. 8 lug, 14 bolt, everything heavy duty, but 3.73. i was hoping for 4.10s, but of course cant get what you want.

i can guess that since its a suburban, it was meant for family hauling/towing, so itd have taller gears instead? i dont know.....

Not really Niether gear set is considered more "heavy duty" than the other

according to the manual, 3.73 can tow 8000, 4.10s can tow 10000lbs.
