body mounts...rubber or polyurethane?

[Ken B]

Looking to replace cab mounts on my 81 C10, which is better rubber or poly? I need to replace bolts too, any kits that replace everything?

The Ploy last forever, but the rubber “feel” better. They have some bounce when driving.

I am leaning towards rubber. Replacing 1981 bushings in 2020.....also heard poly can squeek

I have a squeak. I feel like it’s my tailgate. But with the exhaust and 2 12s hitting I don’t notice a squeak most days lol.

I'd recommend rubber over poly. I did poly and there are squeaks and it's a little harsher than it was with rubber.

rainy day here in INDY just doing research,,,,,I just need to see who makes rubber, lots of poly out there

The rubber is really hard to find for any kind of decent price. I replaced all of mine with poly and it isn't harsh at all and still has plenty of bounce and give. I ordered mine from summit and just got a tub of their unbranded silicone grease at the same time. Used the grease liberally during the install and have zero squeaks.

Steele-Rubber has mounts, seals, etc.
