I've been watching the Mopar suspension world for a while. I have a shelf full of parts waiting on my 71 Challenger...

But I always thought having a Delrin bushing in the upper control arms would be a great benefit to handling, and up until now nobody produced them.

I was googling and found that Performance Online has a set, with delrin bushings.

Has anyone used them before?

and using the Bergman lower delrin setup it should make for a nice tight package?

What do you think?

I think they would be quieter than the squawking polyurethane bushings. Delrin is amazing stuff. High load ratings and inherent lubricity.

The spherical ones get loose over time. Mine are

From circle track racing they have noticed the higher quality, more expensive upgrade sphericals last longer.

I liked the nylon kit from firm feel:
