Need help identifying springs
 

I found some rear springs that were so new that they weren't dirty yet on a 914-6 conversion car that had been rolled. They are on koni shocks with the fixed perch. They are bright yellow, about .450 wire and about 9 winds. They have a small blue part#, HD S-2 stenciled on them. Anyone know what these are?

Thanks:confused:

Help! Please. Someone must have an idea of at least who manufactured these.

I have no idea. But then, I had no idea what my rear springs were, either. Find a friend with a spring tester and see where they rate. I would test them at three different compression positions to see if they are progressive.

Good luck!
