Noob suspension mistake(?)

[Afiggis]

Please explain why urethane is better. I get that it’s stiffer but isn’t it too stiff? And noisy to boot?

1. Easier to install

No press needed if the original shells aren't damaged
No special tooling needed
No requirement to torque the suspension components at normal ride height
​

2. Longer service life--doesn't rot like rubber

3. Tends to be firmer than rubber--suspension doesn't flex and screw-up caster 'n' camber 'n' toe

Too stiff? Not any time I've used 'em.

Noisy? I had one installation that squeeked. Yup, you've gotta grease the ID and the OD of the bushing during installation.

For the record, the ripped rubber bushings on my K1500 are WAY noisier than the Poly bushings I had some squeek issues with.
