did varrible rate coils make? My older Duff stuff is stiff

I got there 3-1/2'' and I'll say the ride is much better then stock for street. off road well take a look at my gallery.

Love the ride of my WH progressive 3.5"s

I went from stiff stuff to progressive too, and love the difference. A lot less complaints about teeth jarring and breasts bouncing in the back seat.

The breast bouncing is a good reason to keep the stiff ones (springs, lol!)

Depends on who's brests they are...New springs it is.
