Superlift "Superide" springs....

I found a good deal on some Superlift 2.5" springs, F&R, but I'm a little thrown off by the description. It says, quote, [bold]"These Superlift Superide lift leaf springs feature a spring rate that is reduced as much as possible, to emphasize suspension travel and a more compliant ride." [/bold]Umm, I don't want a squishy ride, especially when towing. Has anyone had expericience with these? Are they really squishy or is this just marketing lingo?

Do they give a numeric spring rate? They sound soft to be flexy and nice on the road.

If they're anything like the packs they make for the smaller yotas, they'll pretty damn stiff. For what that's worth...
