As the title suggests. I am bouncing back and forth on whether to order all rubber suspension bushings or go poly. I had Poly suspension bushings on my 1 ton ford and they seemed to wear faster than rubber and were stiffer.
My goal is to rebuild front and rear suspension in total.
Thanks for reading / replying,

No poly for the rear strut rods. Go rubber or heim joints.

Polyurethane bushings in the control arms will definitely make it ride harsher. I used poly bushings on the sway bar links and did not experience excessive wear.

My experience with using rubber bushings on my '73 A-arms is bad. After 2 years, cracks develop. I swear I install them properly, and tighten everything up with weight -on-wheels. I'm going with poly bushings next time, and use Moly-B for squeak-free operation.

The Corvette shop owner in my locale (near Ann Arbor, MI - "Bobbies Corvette") swears by rubber components. He said that the poly parts are stronger and will likely wear better - but, that they are so harsh - and, he has had so many customer complaints - that he strongly recommends the rubber steering/chassis/suspension components to avoid disappointment, and that the latest rubber compounds are superior to the old days from a performance and durability standpoint.
Info only - I am just relaying what a recognized C3 Corvette shop owner advised me...and, with that reflexive "please don't ask me to use poly" look in his eyes.
Good question, though.

I can see using poly for sway bars, but I think rubber is better for just about every thing else.

So I see the discussion begins again. This topic has been a staple of all forums kinda like should the toilet paper roll from the front or the back ( from the front of course duh!) I had the same dilemma and I solved it by figuring that the rubber bushings had been in the car for the first 40 years so who I am to argue with that, so rubber it is for my 75

I have poly and very unhappy, I was told by VBP the bushings I have in Trailing arms are good for maybe 8 to 10 years but will not last. The fiberglass spring bushings and the rubber where they mount to differential just fell apart I had to order the kit to replace them. A friend of mine had all new products for one we were building and the poly bushings got hard and crumpled in the box. When I replace next time it will be stock stuff. I also have all kinds off popping and squeaking from front suspension. It is all poly.

Pick you product carefully. Both rubber and poly can come from bad manufacturers and not last.
Only 34 years together

I used Energy Suspension several years ago. No problems yet. Ride may be a tad stiff, but handling is WAY better than before. Used the lubricant that can in the package, no squeaks or creeks or thumps. As was mentioned earlier, quality comes from reputable suppliers/manufacturers.
