I have searched for hours and can't figure out which coil spring is softer. I have a DK code on my 99 3.0 auto 2wd extended cab. Looking on rock auto it shows coil springs for DE, or 2ACJ. That means I should go with the 80660, but I want a little softer if I can. I just want to know which code had the softer springs. Can anyone answer this?
Which is a softer spring code for coils, D, E, 2, A, C, J? This is the only question I need answered.
