do springs get soft over time

[stssilverado]

my 68 convertible sags in the ass. it's a monoleaf setup and the rear is 1" lower than the front. do springs get old and "soft"?

i'm looking at the hotchkis mono to multi leaf springs. has anyone had experience with the conversion? is there a better option (other than an expensive 4link)?

thanks for the help.

Yes springs are a fatiguing part, and will lose their spring rate over time. You should also strongly consider replacing the shocks while the rear suspension is apart.

I'm guessing this is a Camaro? As far as multileaf springs go, I think the primary outfits are Global West, Hotchkis, and Detroit Speed & Engineering..I'm sure there are others. And there are quite a few dealers for all of these. I converted my car over from mono to multi using Global West leafs and the Detroit Speed conversion kit. You can either reuse your monoleaf shock plates and just get new shocks, or you can go with a multileaf shock plate and multileaf shocks.



My buildup in my signature for a bit more information.

Actually that is incorrect, springs do not change their rate over time. The free and loaded height will change, however. Rate remains the same.

Sounds like a song

I agree
