Polygraphite or Stock?
 

I'm shopping for front-end rebuild kits, and I've been given the opportunity to either go with polygraphite or stock rubber.

I've heard that the polygraphite parts can be known to squeak a bit. Is that true? Is it anoying? Right now the only reason to go with stock is that it's about $30 cheaper. Since the polygraphite parts don't deflect (from what I've heard) then are they the better route? Anyone have experience?

I have poly on my Camaro and I like them. They do squeek a little, but not enough to really bother me.

I put the poly ones in my Monte Carlo SS last winter. They don't squeak. Be sure to get the special grease (it's almost like glue) and coat everything WELL, and you should be ok. I went with the poly because I don't need the practice of changing them often. I'm in the middle of doing my Chevelle now, but progress is slow because I'm sandblasting and powdercoating all the parts. Hope it will be worth the effort when done.

Not sure what polygraphite is (implies graphite lubricated?), but I have polyurethane everywhere on my 69 C-10 -- sway bars, track bar, rear control arms, cab mounts, and also on my Maxima's sway bars. Some come with a lubricant, but I've also used distributor cam grease and have never heard a squeak from any of them. By the way, the only bushings on my front suspension are for the sway bar. My control arm shafts don't have bushings, but instead are threaded on each end and rotate inside large cap nuts. There are grease seals between the nuts and the shaft. Is the C-20 different?
