New leafs too high, how much will they settle?

What springs did you install?

How much they settle depends a lot on the quality of the springs. I have a set of Mopar Performance springs on my Challenger that probably settled and sagged at least an 1” or even 1.5” within 6 months to a year. But the AFCO’s on my Duster probably haven’t even settled a 1/2” in several years.

A 1” block isn’t a big deal either, it’s not going to screw up your geometry enough to worry about and they’re fairly cheap and relatively easy to install. You could even install them now and just remove them later if the the springs do settle out enough for you.
