Yes, never again though. They aren't any better than what I can buy now off the shelf. I'd also install coil overs first since the available springs will give me any ride height and rate I need.
Which coil springs are the softest for a lifted TJ?

Who the us is does little to change the combined experience level. But, I am one of the US in that group.
It changes the ride height.
lol not the issue when riding on the bumpstops and their 50,000 lb/in effective spring rate
You really need to read more about how things work or switch to the other forums with a response time equal to Biden's #BareshelvesBiden.
Guess I need to draw a picture for the crayon-eating parrots out there. My suggestion for a ride-quality test drive WITH NO SPRINGS INSTALLED was obviously a joke. Of course it'll buck like a go kart with 0 uptravel from sitting on the bumpstops. Go drink a beer and keep watching out for lizard people.
Personally if I was interested in testing lift height vs ride quality I'd just use a budget boost. I think it's been done once or twice before.
That is essentially what I did. I went from 140 springs with a 3/4 inch spacer to 160 springs without the spacer. Same shocks. Ride height was about the same.
the problem with describing this with F=ma is that "F" hides that there are two forces in play here. There's a -kx representing the spring, and a -cv representing the damper.
ma = -(kx + cv)
m=mass
a=acceleration
c=damping coefficient
v=velocity
k=spring constant
x=displacement
If you're slowly crawling over a rock, the springs will play the dominant role in how far the rig leans over because the piston velocity in the shock is very low and kx is the dominant term in the equation. But if you encounter a hole or bump with any speed the shock piston will be moving very quickly, "x" will be relatively low but "v" will be quite high, and the force exerted by pushing a piston with tiny holes through a viscous fluid will completely overpower any difference made by a few pounds per inch of spring constant.
I don't have a dog in this fight. I just did a spring swap which can been be found here:

I can tell you from my experience in a TJ specifically, that while I could tell the difference of changing to a new spring, that change was negligible. I ran both sets of springs without shocks and both sets with the brand new shocks.
The Metalcloak springs were far stiffer than the Currie springs without shocks. With shocks, the change was negligible between the two.

I agree. I’m just being a smarta$$. I actually just did all new suspension. The new control arms helped more than new springs. The biggest change was going from RanchoRs9000xl to Fox 2.0 shocks + proper shocks and bump stops setup.
That’s interesting. I went from bilstiens to rancho rs5000x, to fox 2.0, and settled with rancho 9000xl (currently still running these). None of these options were fantastic.
Later, I rode in Chris’s outboarded rig and that helped me understand how fantastic the ride quality could be. Absolutely unbelievable!
