I recently bought spohn tubular a-arms along with a sway bar and a factory style coil spring. Here are the a-arms that I bought...

The a-arms mounted just fine into the car however, the coil springs are a different story. I compressed the coil springs as much as I could using an internal spring compressor. I followed the tutorial on this thread that I found about how to install new coil springs.

The problem I am having is that even with the springs fully compressed, they still won't fit into the pocket on the a-arms. Has anyone had this issue installing them before? Any advice or tips would be very much appreciated.

 

Same problem here!

 

Spohn has had troubles with K member, a arms and wonder bar. Detail more what you mean by won't fit. Is the id of the spring pocket too small? Does the spring not line up ?

 

Got mine installed.

I will note that I have a sway bar made by Spohn and personally it doesn't lineup with the linkage. It puts it at a great angle. Maybe due to now needing the caster and camber set correctly with an alignment.

Good Luck ~
