Strengthening rear suspension for towing

[Yukonman209]

So load leveling shocks. Can you take a pic that's more in line from front to back? What do the truck coil springs look like? See this driver's side pic for what the Nivomat shocks look like (you don't have those), and where the coil springs are on top of the axle.

Here's what the RPO sticker looks like:

Look like you had OEM nivomats ZW7 and G65 and they were replaced with whatever that coilover looking shock is to compensate for being a traditional dampener.

I would swap out your normal coil springs with one from a model without Nivomat, Autoride, etc or simply replace the Nivomats although that’s probably a more costly proposition

My observation as well. We can't tell if the springs were changed from the softer ZW7/G65 spring setup to a standard spring. I'd probably just add airbags in the coils and air them up as needed.

I was never a fan of those spring over shocks after I tried them on one of my Squarebody Suburbans. Prefer air shocks or air bags.

What is a good site for me to look up good springs because I looked on Amazon and they all look the same to me and then I read that on a certain year you can get the springs off a Dodge and fit them on but I don’t know how that would work out

Moog 81069 rear coil springs, these are the equivalent of GM HD springs used on Z71s and later generation ZW7 without Nivomats. 45H2164 for ACDelco Professional.

Isn't that Moog number the right one Ron? @OR VietVet

Same MOOG springs I use on my rig.
