1952 Cranbrook rear leaf spring question

[Ruby 52 Cranbrook]

I picked up a set of leaf springs from a 1950 Plymouth Super Deluxe. Compared to my original springs, the 1950 leaf springs had more unloaded arch by about an inch than the originals. They also had what appears to be a protective covering around both ends more than one foot towards the center. I reassemble with the best of the bushings and the car sat 2-3 inches higher and the springs were not compressed past flat as the old ones were. I am happy with the results

According to my Hollander Interchange Manual, Rear Springs for a Plymouth will work for "1937 - 1952 All Passenger, Utility Sedan. & Sedan. Delivery."  That said, I think you have a lot of options!  Good Luck.  :)

Thanks for the inputs!  The springs I found are in Southern California for $25 for the pair and I need an excuse to drive 4-5 hours to look at the other parts available. I really don't need anything but once I see what's there, I may find that I WANT some parts. In any event, having spares to work from can't be bad. I will probably end up using a spring shop. I have 2 experiences with leaf springs. 30 plus years ago I brought the front springs to a 1940 Ply pickup  to a local spring shop in San Jose. They added a missing leaf and they fit and worked great. Unfortunately they are not around anymore. Last year I bought some rear leaf springs for my 1956 Chevy from a frame shop and after 3-4 "re-archings", the shop could never get them right. I ended up buying a brand new set that worked great. I think the comment about tempering by mvair is right on.

The P20 springs will fit perfectly, but are they any better than the ones you are replacing?    If you want a lasting repair have a GOOD spring shop work them over for you.

Let us know who you use, if anyone.  I am close to you, in Mt. View.  I purchased rear leaf springs from Eaton Detroit Spring years ago for my 52 Cranbrook.  It always sat low from the get go.  I don't mind it much as I like the look.  But they are running almost flat, does not really seem like the correct springs for the car.

Good luck,
JD

In Northern California I used Valley Spring Works in Dixon. (Between Sacramento and Vacaville near Davis) http://valleyspringworks.net/ He re-arched and re-tempered the springs on my '41 to factory specifications. I suggest using a service like this. It is important to have the springs re-tempered to maintain the arch after bending. Not all shops have the ovens needed to do this.

Hello all, My rear leaf springs seem to have lost their "springyness", The car appears to ride a little low in the back although is made it from Pacific Grove to Big Sur with 2 extra people in the back seat. I just looked again and the springs are slightly beyond flat so the arch is now facing the ground.
I found some springs for a 1950 Special Deluxe 2 door and was wondering if they would fit. The price is right. Also are there any specs to measure the correct position of the body to the ground or other pertinent dimensions.   Any good spring shops in San Jose/Bay Area, CA  Thanks
