Suggestions for upgrades to tow? 79 C10

I'm a big fan of airbags for the adjustment of having a comfortable stock ride and then airing up to haul a load and also maintain better weight distribution on the front truck axle. 6000# is getting up there for a 1/2 ton truck in the mountains. I would ensure top notch engine and transmission cooling and 10ply tires that are properly inflated. There are also some givens such as functioning trailer brakes and a brake controller.

X2 for the HD brakes front and rear. Most rigs can get a load moving, but getting it to stop is a different story. If you want to keep your set-up old school, you can’t go wrong with T400 and gear vendors set up. Gives you under/overdrive options or 6 gears. The T400 is bullet proof if cooled with its own external cooler. If you’re towing 6k lbs consistently, 410 gears for sure.

And I agree with above about HD springs and possibly airbags depending on your needs.
