74 Dart - Very stiff ride - Help

"very stiff" is subjective. Most of us have the opposite issue...but...

What size torsion bars are in the car? You can look at the end of the bars where they mount to find the identification numbers or measure the diameter. I know that you can make the suspension like a rock if you pre-load the springs too much.....you can back them off a little to see if it changes the feel, but remember that when you loosen them it will change the ride height and it will need an alignment.
>/flashback> When I was 16 and changing the brakes on my 75 duster I found a bolt that appeared to be loose in the front suspension on each side...so I tightened them, only to find that when I let the car off of the jack stands it was so tight that the front end wouldn't move even if 2 people were standing on the front bumper</flashback>
Man, I must have tightened the crap out of those things :lol: oh well, live and learn ( no FABO back then )
