CargoMaxx Rear Coil Spring Upgrade for Towing

[Nibis]

I put the Cargomaxx 35% springs for the 4th Gen, to minimize lift. The springs are great, truck handles so much better loaded, and barely different unloaded, compared to stock. We pull a 3 horse trailer, normally with just 2 horses, sometimes 3. I would recommend these to anyone. Pic unloaded, and loaded. I had a hair up my you know what, and traded off my Laramie, but if I still had it, I'd be putting these springs in too. I tried the 70% first, stiffer than I needed, and ridiculous lift. The 35% are perfect

Have you ever used a wdh pulling a horse trailer?

Did you get any lift in the rear? And what part number did you get?

I am also wondering about this too. Is it standard suspension or off road suspension?

Big +1 on the Timber Groves. I’ve been using them for 4 years with an 8000 lb TT. Great lift assist and better suspension for towing. If I don’t air then about 5psi when unloaded then I at times bottom out (RR crossing etc) which isn’t great because they replace the bump stop. I am considering a dual rate spring to see if it helps as well because I still get jarred on bridge separators and some other rough highway (why I found this thread recently).
