Re: Polly vs rubber

Several years ago I installed the Energy Suspensions, black k, graphite impregnated bushings. My kit came with all new hardware but I found the bolts to be inferior. Didn't use any of the bolts and got all new bolts from AMK products. They are just like the original bolts.

Re: Polly vs rubber

For body bushings, I think Poly would be great.

As far as control arm bushings go, why bother with poly control arm bushings with the excellent Delrin bushings that are out there today..

I tried poly rear control arm bushings on my 64 Pontiacs four link years ago, they were terrible. When turning off a hill onto level street it felt like my rear window was going to pop out! I ended up making rear control arms using Currie Johnny Joints, big difference!!

Re: Polly vs rubber

I called Energy Suspensions. The black bushings are no longer graphite impregnated.

Re: Polly vs rubber

I used rubber, and broke or spun the nut on every bolt.

Wonder why? I thought they were great they even felt kinda slippery and no squeaks.

I assume you broke them on disassembly. Before I removed my old bolts I drilled small access holes above and doused them every day for a few weeks with Kroil. Then when I a tally went to remove I barely broke loose and then retightened, broke loose a little farther and retighten again going a little further each time until bolts were removed. Only spun one and was still able to get that bolt out by jamming a big screw driver through the drilled hole and wedge against the caged nut.

Re: Polly vs rubber

Know what you want to do with your car before deciding on bushing usage.
I used urethane and graphite
They looked same and found when each got old they bound up.
They need grease fitting system.
Switching back to rubber on one car. Car creaks.
Converted my other to del a lum.

Re: Polly vs rubber

Front suspension I replaced the worn out rubber with UMI tubular A arms and Delren bushings. Out back more UMI tubular stuff but with poly bushings. The rear feels a little firm over speed bumps otherwise the ride is great. Fat sway bars F&R and Monroe Gas Magnum shocks.
I need to replace all my body bushings but will wait until I get body work done.

Re: Polly vs rubber

I can give you my recent first hand experience. I had old, rubber body mounts and I replaced them with Energy Suspension poly mounts.

I can absolutely feel the difference in how much the body jitters when going over harsh bumps or train tracks. The rubber definitely dampened some of that. I personally would still go poly, but there is a difference. Now what I have yet to find out is how much body mount flex there is as before the driveshaft would touch the floor a bit in certainly situations.

I installed a set of graphite impregnated Poly bushings from PST in my Monte several years ago.
Mark Savitske had recommended using a graphite bushing and those were what I went with.
It looks like they are still available from PST for your '69;

Good call Guy. Just checked. A set for a 69 is $100.00. Those and some AMK bolts and you are golden.

Thanks for the warning. Seems no one is immune to cost-cutting.

I thought I read somewhere (maybe here) that Energy made all the bushings for PST?

That could very well be true but would be odd that they would no longer do the graphite impregnated bushings in one line but still in another.
