I have three front springs for my LJ. Stock, CC780 and CC782. With the same shocks the stock springs ride okay. With the CC780 the dual rate springs ride on the stiff section and the ride is rough. The CC782 springs run in the light rate section and the ride is smooth. The springs obviously change the ride. I am not reaching the limits of my suspension at all.
The ride height does change from about 32.5" at the fender to about 33.5". It's still very roughly mid-travel on the shock.
What bothers me about these threads is
@Fargo and I have these real experiences that show in some arguably tiny fringe cases that springs do change the ride and people say it can't. It just doesn't seem like reality to me. I completely understand the desire to push people to tune with shocks but that doesn't need to include dismissing the springs in such extreme terms.
