Suspension Bushings - rubber vs others such as polyurethane
Permalink  

Hi everyone, looking to freshen up the front end on my 69 SS over Winter ( ball joints, tie rods, control arm & sway bar bushings).  Car has only 60K original miles but 54 years has left them a bit dried out.  Posted here as F body is very similar to the X car suspension. 

 

Being a factory SS I think I should stay stock (ie no tubular A arms etc) but was wondering if CPP Polyplus, PST Polygraphite or Energy Hyper Flex in black would be a good update while still looking factory?  Not looking for pro touring levels but just figured while all apart, decreasing flex while still having a decent ride would be a good compromise.  Car is currently running stock height springs and 60 series BF T/As. 

Any advice is appreciated as online search gives no clear direction.

I personally would never use poly again . Too harsh a ride and really tough on suspension and frame. Just not enough give. I've tried them. Unless you are doing a full on pro tour frame off. Just stick with stock good moog ones.

 X3 here. A good set of stock bushings would be my vote also because of what Beaumontguru said.

I put the poly bushings on my 67 camaro. Also poly body mounts and rear spring bushings. I would not recommend. They give a harsh ride on bumps and are very prone to squeaking and squawking. These old cars were meant to have a little give so stay away from the poly if you are building a driver not a pro-touring car.

As above, probably smart to stay stock.

The one place you might still consider using poly is in the front stabilizer bar mounts and endlinks.

Thanks everyone, really appreciate the feedback! I certainly dont want to end with a harsher ride and/or more noise as Im never going to go slalom racing or anything similar. I like Marks idea of maybe just upgrading sway bar bushings as thats easy to change out if needed.

Ive heard I should stick with Moog parts so Ill have a look at Rock Auto to start.

Thanks again!

Remember not to skip having the car siting with all it's weight on the suspension, when you finally tighten all those bushing through bolts.

 Thank you, did lots of research but will my first time attempting myself so tips are always appreciated.  Almost too much info out there but even though older, this video series seemed fairly comprehensive.
