Re: Stock Replacement Spring Info
Heres a table of which springs trw/moog offer as stock replacements and their aplications. Now the table doesn't include every vehicle as the information wasn't provided via there website, and some of the data that was provided doesn't seem real accurate in a few cases.
Overall though most of the data seems to take sense, though none has been confirmed first hand. Once again this is all based off of the information I have collected from the federal mogul website.
Feel free to correct the table of any possible typos or new/unentered data.
To access the original source of the information follow these steps:
1. Click this link http://www.federalmogul.com/en/After...s/Catalogs.htm
2. Select make/model lookup
3. In the window that opens select your vehicles information.
4. Click "steering solutions"
5. Click "front springs"
...

I know that had to be a headache. I'm going to take a look at it when I'm not about to fall asleep.

New information. I'll try to compile a bit of a sticky when I return home.

Re: Stock Replacement Spring Info
Does anyone happen to know what rate a spring tagged with "NNM" is?
Its my rear spring on my 85 T/A. Compressing it(outside the car) next to my new UMI rear spring(200lb) it feels a little stiffer - which is disappointing.

Re: Stock Replacement Spring Info
Is there a way to correlate any of these part #'s with NNM?
