those look like the Energy Suspension pieces. I have several sets. You are right, they fit better as far as collapsing, but they seem to need to be a larger diameter on the bottom. When I went thru the suspension sweep, they would ride off the theaded ball joint receiver. That is why I opted back to the ones that came with the ball joints.

I took a ball joint and housing to several local automotive parts stores......without an application (year/make/model)....the counter people were lost......nothing but blank stares.
