Spring assist choices. Airbags, Timbren or Sumo Springs?

I'm looking for a little help to choose a spring helper. I have been having more than typical axle wrap issues but now I'm looking to tow a trailer 2000 miles. So if I can solve many issues at the same time it would be great. So I hope to have a reasonable daily drive feel after I'm done with this distance towing. The axle wrap has been pretty extreme where it actually binds up the axle and driveshaft. Causing it to lunge forward 1.5 ft when I let off the brake. Dealer has told me to basically screw off. But I have a friend at the dealer now. So I might still try and see if there are any options there.

Question:
So I have read all the average info and install vids. That's all good. But My impression is that airbags would ride stiff, am I wrong? Sumo springs vs Timbern, these seem nearly the same product but my ride like airbags? Yet Timbern has a flip kit. So what would your choice be?

Now I have a Timbern flip kit but it's missing parts. 1 plate and a few u bolts. But I think I can fix it for about $70

 

How big is the trailer you are towing (trailer weight when loaded and tongue weight)?

Is the towing a one time deal or do you plan on towing semi regularly?

Airbags/helper springs are great for addressing payload issues but not the best choice for towing. A weight distribution hitch is the proper solution for towing.

As for the axle wrap. Are you running the factory leaf spring? Do you have a lift?

 

Well, the plan is 12ft Uhaul trailer if my stuff doesn't fit in the big moving truck. The stuff I might take wouldn't be that heavy just large.

Would I tow regularly? Eventually when I get or borrow a boat.

My suspension is 100% stock and I get a lot of axle wrap if I stomp on the brake anything more than grandma easy. I have no lift at all. No blocks or anything. In fact, it actually sags over an inch and the leaf spring looks flat. Currently at 88k miles. Previously a rental truck but had no hitch.

I'd really like to solve this in the next 2 weeks before I move. Hopefully under $500

 

Since you have the timbern kit, if you can come up with the parts your missing that'll work.

When you start towing more regularly I'd look at replacing the leaf pack and getting a weight distribution hitch if your trailer tongue weight causes your suspension to sag.

The idea behind air-bags is that you can adjust them based on payload so they should ride like stock. If it is too firm then they are probably over inflated for the load.

 

Well I was thinking to avoid airbags. As I'd like to lift like 2in at some point with bilstein 5100. But would the airbags be a better option?

 

I towed a 23ft travel trailer that had a 600lb tongue weight for 4 years/8,000ish miles and have never run airbags. Again, I don't think they are the proper solution for towing. You have the timberns and have a plan for suspension work in the future. Run what you have and save the money you'd spend on airbags for a new leaf pack when you lift the truck.

 

Blue Sumo Springs here with new U-bolts. I added a little torque to the new U-bolts. I don't tow anything but I do load the bed up pretty good. Generally I like the ride better with the Sumo's. It takes curves better, less lean. There was such an improvement that Mrs JGO noticed the difference. The only rally rough ride I get is over poorly maintained railroad tracks, the sharp drop can be jarring. I would buy them again.
They were a breeze to install after I was able to get the original U-bolts unfrozen and off.
