After blowing out my second set of stock shock bushings I decided to put in a set of Energy Suspension polys. I used 9.8101. They are smaller diameter than the stock but the nipple size was correct along with the the ID. I used a large flat washer between the cap and top bushing to help put a little extra pressure on the bushings. No noticable differnence in ride quaility. I'll give an update in a couple of weeks to let everyone know how it works out.

It's been a couple of days of commutting and a lot of big speed bumps. (Orlando is speed hump crazy) and the new bushings are staying put.

I put ENS donuts onto the HD Bilsteins and it actually smoothed out the ride quality a tad. Poly shock bushings do not deflect as much as rubber bushings, so the shock dampeners work more efficiently.

My Edelbrock IAS shocks come with poly bushings, one more reason why I like them over all the other aftermarket brands. Now only if Edelbrock would make them for 03-up Panthers...

What was happening to the original style bushings?

The upper bushings were getting squeezed out from underneath the cups. When they got bad enough the cup would actually hit the shock mount.

Wow. Could the cups simply have been torqued on too tightly? I understand there is supposed to be some compression movement left over to allow for absorbing any transmitted vibrations... if they bulge out too much during installation, it's too tight.

The nut hits the stop long before they begin to over-compress. I've had Panther platform cars for 10 years now and they all use the same exact cup and bushings, including the Marauder, since 92. I've never had the problem in any other car but I've never had a rear suspension set up so stiff either.

Could this be a Tokico issue? (ie. shaft diameter, or length of thread in the shaft, etc.)

As tempted to say that as I am, I'm glad I didn't and you DID! ;)
