Variable rate rear springs

[kevin588127]

I currently have a 22 2500 CC hemi (non off road package) that is bone stock down to the Firestone HT tires. It has 14K on it with a fair amount of that towing a 10K bumper toy hauler. I've been very happy with it but have noticed in the last few months that the unloaded ride is getting a bit worse. I'm experiencing some proposing at times. I'm guessing that the stock cheapo shocks are probably some of the problem. On my previous 1500 ram, I had a great experience with tuff truck varialbe rear springs and bilstein shocks. It rode better empty and had less squat while towing. I loved that setup. I thinking of going the same route with this truck and wondering if anyone has gone this route. I am seeing tuff truck and cargomax offering a variable spring. I am looking to maintain factory ride height and not looking to "increase" capacity, just looking to improve the ride while maintaining stock ride height and capacity. Cargomax lists theirs as a 35 percent increase in capacity and that kind of concerns me as to how it will affect ride quality.
