Stiffer linear rate springs

[Robalo2718]

So this is more of a hauling than a towing question, but I was directed over here when I posted in "suspension."

Please see quoted post and share any experiences you might have with the below mentioned rear springs or other linear rate rear springs. Thank you.

I ride around with a 300-900lb load most of the time and the rear sag is killing me. I'm looking at two options for stiffer rear linear rate springs:

1) TufTruck 1211

TTC-1211 - TufTruck heavy-duty rear coil spring suspension

TUFTRUCK TTC-1211 Professional heavy-duty rear coil spring suspension kit for RAM 1500, designed with TOWING IN MIND.

2) Dayton 350-905HD

Aside from the few odd posts here and there, forum information on these is scarce.

Can anybody help me out with reviews, experiences, specs? Would be greatly appreciated. Thank you!

I am planning on going with either 35% or 50% linear spring. after watching this video, and his explanations, I think its time. I still need to get to a scale to see my unloaded weight though to see if the 35% or 50% is a better fit for me, not sure if the 70% will just make it feel like a 2500?

Did you ever install springs? Came across your post a few weeks back looking for more info on the cargomaxx.
Ended up ordering the 35% variable ones.
Have the rough country 3.5 lift level installed. The back end always look a tad lower just because of the lines of the truck and when I had the bed full or my camper hooked up i was getting a bit of squat i didnt like.

I can tell you they are definitely stiffer than the factory and empty I went from 40¼ ground to top of wheel well to 41½ inches after.

To clarify, stiffer meaning I had to compress them alot more than factory.
Ride around town so far I am noticing minimal difference from factory springs.

Any update on these? I have horse trailer I pull, and would like to compensate for the drop, without the use of air bags
