Towing my tractor

[stutaeng]

I was going to suggest re-gearing to at least 4.10, but you have to do both axles, unless you will drive it exclusively on 2wd. Otherwise tow in 3rd as was mentioned.

I think your weak link will be the transmission. Get the largest transmission oil cooler you can fit in there. I think I read someone here said they installed a Duramax trans. cooler? Maybe find one at your local wrecking yard for cheap.

Is that really a heavy half? Those are actually a lot more capable than a regular half. OP for stopping look into the hydroboost swap. If you're lacking spring, get a true 2500 leaf pack. Tow in 3rd, not OD and go for a quick test drive all the way up to highway speed to see what you think first. Make sure the tires are maxxed out on air too. If you have a WD hitch, this will be your saving grace. Sounds like you won't have a ton of wind resistance so that's good.

Yeah, it is. 8-lug 2500's GVW is 8600+
Most 1500's are 6800ish. That 2500LD is smack in the middle. 1500 frame, D rated tires, thicker torsion bars, HD brakes. (What's the RPO code? F44 I think?) 14 bolt 6-lug rear axle. Heavy half.

Close. My 1500 is/was 6200#, 6600# for a heavy half, and 7200# for a LD2500. Far as I can tell, same front brakes but bigger rears and they do make a difference. Rear axle goes from 3600# up to 4600# IIRC on the LD2500, so probably 4200# on the heavy half. OP go fact check me on your door sticker.

Then my 88 must be a light half - 5600#

Yep, it had the smaller front brakes.

Well, I went to my '00 Denali for my half ton "ish" values. Considering the 5400lb curb weight, GM must've given the SUV's a little extra. At least on paper...

They did, they also gave them an extra leaf in the half ton SUVs.

Whoops, its sideways

And different rear brakes, better that the weak, crummy "leading-trailing" design.

I think the Burbs were 7000# GVWR with 4000# RAWR.
