Hi, new guy here but not new to forums.

I am looking for some advise on where to purchase some leaf springs for my 67' 300. I have seen here that some people recommend purchasing them through ESPO is that still the best place to get them? I can't find them for sale from any of the major retailers online.

I am not looking for some crazy performance I just want my car to ride as good or better than it came from the factory and sit at stock height. My springs are completely flat at ride height currently.

Thanks guys.
 
Flat may be where they should be running, Chrysler springs are not set up like other manufacturers, check what the factory ride height should be for the car before deciding if your springs are worn. Some Chryslers even have springs that recurve the other way at the rear.
 
I am gonna follow this thread as I think I might be in the same boat with my ‘68 300.

Where would I find the factory ride height for the car?

On a level ground location, the rocker panel should be parallel to the flat road surface. As the lower edge of the door(s) should be, too. Look at some old print ads of the cars to see what I mean.

In the FSM, there are dimensions to set the front ride height with the torsion bars. It's kind of tight to accurately get those dimensions, from my experience, but I suspect the main orientation is to make sure the adjustments are the same, side to side, on the front. Using the more common "top of the front wheel opening on the fender" might be different if there's some normal manufacturing variation in how the fender is aligned with the rest of the body.

IF the car's current rear springs have "aged", with the front torsion bars adjusted to match, a new set of rear springs might put the rear end "up" until they settle-out after about 1K miles or so. So you'll probably need to even things out with the front torsion bar adjustment.

With factory springs, there were "std" and "HD" versions. The number of leaves and their size specs are in the FSM, with each side usually being different. An additional 1/2 leaf or so on the rh side to help counteract spring wind-up under acceleration and engine torque.

If the car has factory a/c, it's already got the "HD" front torsion bars, even with the "std" suspension calibration. Additional weight on the front end, due to the weight of the a/c equipment.

Might just need a set of good HD shocks all the way around? Air the tires up to about 30psi, too.

Just some thoughts,

Yes is sits level at ride height. I think i have about 5 inches of uptravel before it hits the bump stops. I have it up on the lift today to change out the 20 or so years old black brake fluid so at some point ill pull the shocks off and see if they have anything left in them. Maybe some new ones will do the trick.
 
You do NOT need to know anything about car height, spring arc radius, or any of that bullpuckie.
Just tell ESPO, the make, model, and year.
Tell them what kind of height you want. Stock, 1" over, 2", over, etc.
Then tell them what kind of ride you want. Stock, HD, etc.
Install the new springs, Your *** end is now your new height.
Adjust your torsion bars for your appropriate stance.
DONE!!
 
Just as polara71 says:
Get the Leaf Springs, Shackles, U bolts and I Bolts from --- ONLY --- ESPO Springs & Things -- 1-800-903-9019 ---
Laura is a sweetheart -- she will set you up perfectly -- shipped right to your door or your shop...... CAN'T Beat it.........
 
When I needed new springs, I just thumbed the Yellow pages for springs and made a couple phone calls and went locally. This was in Chicago 20+ years ago and are still holding up strong today. It was tons cheaper then going with the alternative and having them shipped. Good Luck

YELLOW PAGES???? Please explain to the millennials what this is. Lol

Of course, then there's the other side of the coin... The previous owner of my car sourced the leaf springs from a local shop. A well known and recommended shop at that. The springs were garbage and the shop installed them. They torched the nuts off both shackles ('70 style offset) and when they discovered they couldn't buy new, they cobbed them back together and installed them on the wrong sides.

So... YMMV.

ESPO does them right. Hard to argue with that.

Edited, I thought you were talkin about me, sorry.
