It's going to be a compromise, no matter what. Can't get around that. My F250 rode like a, well, like a truck, my mother would have said "lumber wagon" or maybe "hay rack". But add 2,000+ pounds in the back and it was a Cadillac for ride. Then the weight matched the spring rate better. My first flat bed on the back it really smoothed that truck out.Well that's a little give and take. Softer springs are going to be more compliant which means that on a compression stroke, they transfer less energy to the chassis and keep more rubber on the road but the opposite is true for extension as they are slower to respond. Really the range of acceptable firmness is insanely wide and what you posted is more appropriate for a car than a pickup where spring rate has a lot more responsibility such as the towing and plow cases.
So I guess what it comes down to is suck it up or buy another truck haha. You unfortunately have a multi-use scenario that requires opposing strategy and there's just no way around that. You aren't increasing rate enough here that it will really change handling but you will see changes in ride. It's just the nature of the beast when setting a truck up for both unladen daily driving and loaded work duty.
This is just the opposite - it starts with good street personality and behavior, good ride, but those times it's loaded, have to compensate.
Multi-rate makes sense - we have max tow to refer to there. It would seem that taller springs with only a slightly higher rate might work - more stored energy, when compressed, still high enough.
The Rubicon springs under the front of my 2020 actually did well as far as handling on the road.
They were the lighter of the Rubicon pairs so it made sense they dropped with the weight of the steel bumper, etc. So I had to use spacers to get the height back up again.......leaving less spring travel.
I suspect maybe a phone call to Synergy may be in order. They don't respond to email.
We were fine with the ride the 2020 had after the mods I made on it - even though the rear was a bit stiffer (max tow springs) the front was nice and took bumps and tracks fine. And it was solidly planted.
As is not unusual, you present another "voice of reason"
