Rubber or Polygraphite?

[Jhn824]

Hey guys, will be installing some front end and rear leaf spring bushings on my 65 soon... what's your recommendation on type of bushings rubber or poly? also.. does anyone have any experience with PST's 1.03 torsion bars on these early b-bodies? . .thanks in advance for any advise!

Street cruising car go stock rubber, rides much smoother.

How many watts does your stereo put out? Loud stereo, Poly "Squeek Master 2000", AM radio or no stereo, quiet rubber...

Polyurethane was known to be squeaky, but polygraphite shouldn't squeak. It is polyurethane with graphite mixed in to make it slippery.

I won't ever use poly bushings on another car. As for PST 1.03 bars, I have never owned an early B, but have them in all 3 of my current cars and think they are great. Would think they would perform the same in earlier models.

I use poly on the leaf springs and rubber on the front, but it is a drag car.

I use rubber everywhere other then on my sway bar links and mounting points.

I've got poly bushings all the way around and don't have a clue what all of this squeak talk is.. rough riding?? Mine rides perfect (for me) and doesn't squeak 1 bit, that's not even polygraphite, just regular poly? I like poly but then again I prefer a firm planted ride vs squishy cornering.

I have polyurethane (front and rear) in both of my cars. One is a cruiser and the other is a dedicated road course car. I installed all of them myself and lubricated properly during installation. Neither have any issue with squeak.
As far as torsion bars, the cruiser has stock and the road course car has 1.2 inch bars. I will be upgrading the cruiser to 1.08 to tighten the ride up a little more. My torsion bars are sway-a-way. https://swayaway.com/product-category/torsion-bars/tb-dodge/
Very consistent in handling and installed smoothly. Both have sub-frame connectors and 1-1/4 sway bars. It is nice to have cars that point where you intend without any real body lean.
Your biggest gain to being happy with your car is in your shocks and tires. Stock shocks should be upgraded to at least a mono-tube for current roads and speeds. Tires, we drive our classic cars very little. Don't go for a long-life UTOQ. In most cases, we don't wear out the tread. Stay under a 300 rating for your best handling cues.

I special ordered a Z 28 , 4 speed car new in 1982, only new car I have ever ordered. It came with poly bushing on both front and rear sway bars. It always stayed indoors, never rained on, and only had 22k miles on it when I sold it last year. All the bushings turned to powder and crumbled off. I still have several cars over 50 years old with good rubber. For my mostly street rest o mod cars, rubber.

I prefer rubber bushings. I'm 72. They will out live me!!

The 1.03 tbars on my 64 provide a firmer but comfortable ride. I did upgrade the shocks to bilsteins and added a hellwig sway bar however. I'm happy with the improved handling and suspension feel.
