How to create a 1 directional spring?

How do i create a 1 directional spring(y axis, like a cars suspention)? I can’t seem to restrict the spring joint from moving whatever direction it wants to…

I have played around with the configurable joint too, but even if i lock movement and rotation it still moves whatever direction it wants to. Looks like its bugging out and collapsing or something…

Any1 knows how to do this? Please tell me :slight_smile:

There are 6 checkboxes for constraining springs, xyz movement and rotation. Just check all by Y movement.
