Thanks for the response jbc426. That's interesting about the Caltracs. Were you using the mono leaf springs too? I bought my S/S springs many years ago. I think the spec (description) in the Direct Connection catalog was 3,200 lb. 440/automatic, which is what I planned to build when I bought them (drag race only). Now a Gen3 Hemi, manual trans and street/strip. So I suppose I could use a lowering block, but am concerned it will be pretty stout on the street. You think correct shock selection would make the difference for the street then huh?
