Leaf spring sag

[RecklessBattleBorn]

I replaced my shocks today on the long shot it might fix the passenger side sag in the rear, I knew it wouldn't but it needed done anyway. So with that said I have a 2" sag on my passenger side and need to replace the leaf springs. I've looked into having them re-tempered or re-built but wondering if anyone has a source for a direct fit replacement on a 1950 P20?

I got mine from Eaton Spring.

They were very helpful getting correct fit.

I bought mine at Andy Berbaum.  I also used Ford Aerostar front coil springs.  Car seems high but it's level and it's the right height.

Try John R Spring in suburban detroit, or espo springs and things too.

 

I dont think re-arching is a terrible idea, but I'd consider new ones since these are 70 years old.

you may have a cracked leaf or two. l would first look into getting your stock springs rebuilt. If its possible it may save some cash and square up the rear suspension also improving the ride. The genuine leafs are surprisingly tough. M

To be honest, the rear suspension is in need of updating.  Wheel hop under acceleration in a corner is a real thing even with just my 218. 

 

I'll likely put in some asymmetrical rear leaf springs from a later Mopar, I have a set of A body ones I can use to see how it'll mock up.

 

Might even look at a pinion snubber.  Who knows I might go crazy and think about CalTracs or similar,

When I replaced my rear springs they looked like handlebar moustaches.

I tried going the re-tempered route, but heard they could flatten out again. The only way to help it is to add a leaf.  I ended up ordering lead springs and shocks from Andy Bernbaum.  I’ve since ordered more things from them as well - great bunch of guys! Real helpful and great prices!

I have been using AB since the late 80's when they were the only source I could find for the ball and trunnion parts I thought I needed for my 64 300.  Turns out the old stuff was still good but I replaced them anyway.  Zero complaints and nothing but praise for them since.
