Progressive springs

[Tex06]

Has anyone here used a progressive rate spring for their lift? I'm looking to go SOA in the rear and something like this up front:

sounds like an awesome idea.    just make sure it's the correct lift height.  I can't remember if TJ lift coils give more or less than XJ/MJ lift coils

Street vehicle or mostly off-road? Can't see the point if it's a street rig.

I've been looking into a similar product by Metal Cloak. I think these are actually Dual Rate springs. Metal Cloak makes a 3-1/2 for XJs. I was trying to find a Thread from JeepForums. It was about 46 pages long.  Went over linear, dual rate and progressive. Someone from Metal Cloak posted a bunch of info. Mine will be for the street mainly. They are suppose to be smooth. Still, it would be good to see someone who has used them. I did here the RE has some. Haven't checked that yet.

From what I know (mostly fast cars) progressive springs give you a smoother ride on the road without compromising performance characteristics. Wouldn't this apply here too? Good handling on the road but still flexible off?

progressive/dual rate springs are better at everything      should soak up the bumps on the road like a champ

Called and talked to Adam at RockKrawler. These springs are spec'd like this, I think this should give me exactly what I'm looking for as long as the height is right.

23" free length
8.01" compressed (solid)
135 lbs
165 lbs
220 lbs

I've seen them used for replacement rear springs on pickups equipped with rear coils for better load management when hauling, and of course for road racing on cars front and rear, and for off-roading. But never up front for improved handling on a mostly street truck. Do they exist from the factory as OEM equipment on some pickups?
