And if poly, which grade? Black, blue, yellow?

Going to replace mine soon, as they seem a bit iffy.

 

Pink!!

I'm going down the same route at the mo. I'll look into it and post my results. It may also depend on what you primarily use the truck for. I can imagine different colours = different grades of stiffness for different applications. I'm looking at polybush for ordinary highway use but I have to admit the OEM has lasted 11 years and 121K miles.

PS. I've found some results on a UK website:

Red - (Performance) similar to original spec [would be my choice]
Blue - (Comfort) very soft compound - excellent articulation etc - will wallow like a pig on road
Orange - (Dynamic) not available for all vehicles

These are UK colour ratings so US may be different.

 

If you are doing it yourself and you want easy then definantly go polybush. I went with the orange polybush from lucky8 a few months back and they are great. I use mine as a DD and as bushings need replaced I've started swapping the polybush. You cannot beat their ease of installation either.

 

We have had good luck with the polybushings and Orange are the ones we recommend.

 

Could these cause a vibration if they are in need of replacement? I'm still trying to figure out my vibration.. I'm questioning everything until I figure out what it is.

 

Only poly.
Some stock are actually now made in China and are total crap.

Plus oil leaks eat up the rubber on Stock.

Oil has less effect on Poly
