Poly vs rubber radius arm bushings

[Got4wd]

Any drawback from using rubber radius arm bushings? I am not a fan of poly so I went that way. Oem ford NOS. Now would be the time I could change them out the easiest.

Any drawback from using rubber control arm bushings? I am not a fan of poly so I went that way. Oem ford NOS. Now would be the time I could change them out the easiest.

what vehicle ?? broncos don't have control arms, But I prefer rubber, both in Non bronco and in my bronco,, ,, My radius arm frame bushings are rubber no issues using them ,last set were 22 years old replaced during 2018-2023 complete bronco redo.. I had poly 2 degree , bushings that I recently installed the rubber 0 degree bushings , for pinion angle dial in I have cut and turned so have plenty of caster to play with ,But see no issues with the rubber, FwIw I replaced the original rubber ones in 1994ish with poly 6.25* they were fine but when I did remove them one was spliting down the center,,

Sorry I meant radius arms.

I have no issues with fresh rubber. I think the rubber lasts longer than poly does anyway.
Few years back I was refreshing a 2WD F250 and went with rubber just to make it a little more compliant and give it the best chance at road isolation. Rubber sway bar bushings. Sway bar links I went from rubber/rubber to rubber/ball joint (late model link from I don't know what). I wanted to keep a layer of rubber as isolation to keep the cab as comfortable as I could. I don't recall doing any poly on onything. Completely happy with it.

Rubber bushings can last 30, even 50 years. Poly bushings always felt like a maintenance item.

I’ve been using poly c bushings and rubber radius arm bushings. More flex / articulation with the rubber.

C-bushings are one of the few places where I would consider poly to be a better choice. I will take better caster over improved isolation.
