Suspension Rebuild

[Todd Smith]

I got the K frame pulled out today, and will order a full kit for it this week. What's the consciences Poly or not???

that seems to be the concensus "poly or not" ... Kidding
Rubber is more difficult to change in the lower control arm , seems to cost more & have a shroter life span as if most of these cars will see a ton of miles or severe conditions again , fo rmore performace oriented I would use Poly , for more #s matching show car I would use rubber

Just throwing it in the mix, PST sells PolyGRAPHITE bushings, versus like the polyeurothane 'energy suspension' parts. I bought my leaf spring bushings from them. May want to have a look at what the advantages/disadvantages are from polygraphite to eurothane.

Your car will handle a whole lot better with poly bushings,you dont get the sever deflection with them as you do with rubber.Its all i use on customer cars and have had no complaints.

The polyeurothane bushing do sqeek a little, so I would not suggest them in a modern car/truck with a quiet exhaust.  I added them to my Dakota and now I wish I could go back to what I had.  You should not notice them in a E-body with duals.   I have them in my Challenger and have yet to notice them.

Biggest thing about poly bushings is dont put them in dry,use the lube they send you !!!!!

I used the silicon that came with the poly bushings in my Dakota and about a month later I started noticing the sweeking. Unless you have a grease fitting to lube the bushings, I bet that almost all of them will start to sweek after a short time.  Just my experience.

Just to throw my hat in the mix... IMHO, I liked the parts from the PST link above.  I rebuilt my front end with PST parts when I did my front brake disk conversion.  I updated to stiffer torsion bars, sway bar, and replaced every bushing forward of the firewall.  The polygraphite had a great feel and didn't squeek for the 2+ years of daily driving before the car went into storage.  It is now 99% disasembled, but I am planning to put the parts back on and build my rear suspension with similar parts

Ditto to all the posts above...if you are building a show car, stay with rubber.  If not, by all means go with the poly

I went with rubber on control arms, struts and poly on sway bar bushings and end links.  Didn't want the squeaks.

 :clueless:Quite exhaust?? What that? That's one of those muffler bearing things --Right?

Thanks for all your input guys. Polyeurothane it is. your never gona hear a little squeek with the motor I'm building. Grease fittings sound like a good idea in any event.
