Rubber or urethane bushings

I am getting ready to redo the suspension on my truck and am not use if I should use rubber or urethane bushings on the control arms and trailing arms. Will the truck ride real rough with urethane? I want it to be tight but not teeth rattling.

Also, where's good place to get them. Napa only sells control arm shafts and they are pricey!

Thanks!

Re: Rubber or urethane bushings

It will be a more firm ride,but not really harsh.I like urethane in the suspension,but not the body mounts.

Re: Rubber or urethane bushings

What suspension parts can you replace with urethane besides the trailing arm bushings?

Re: Rubber or urethane bushings

FL -= you can buy almost every bushing for these trucks in urethane
I agree - I am not a fan of urethane body mounts - just to stiff - if you just want to race the truck go for it - daily driver no thanks - they also can have a tendency to squeak more than rubber bushings

Re: Rubber or urethane bushings

I prefer rubber bushings. I have used urethane on other projects and regretted it: harsher ride and noise issues.

Re: Rubber or urethane bushings

Same here, I have had bad luck with poly, I could not stand the noise. I have tried first dry graphite lubrication and when that didn't work, I greased everything up and it still squeaked off and on.

Re: Rubber or urethane bushings

Rubber worked for years from the factory... I would stay with them.

Re: Rubber or urethane bushings

I prefer urethane. I have used both but just like the feel of the urethane ones my 2 cents.

Re: Rubber or urethane bushings

I have urethane mounts everywhere in my truck, springs, motor mounts, body mounts, T-case. They are way more durable then rubber. Rubber these days is such poor quality. I can't hear anything over the exhaust so I don't care about squeaking. I do feel the cam lope through the motor mounts at idle but it's a truck not a Cadillac.

Re: Rubber or urethane bushings

when you install them, grease them, and their pins/spacers washers etc with white lithium grease. haven't had any of mine squeak... to me it doesnt feel for firm, it just feels tighter and more responsive with urethane.

Re: Rubber or urethane bushings

urethane lasts longer and tightens up the chassis (less flex than rubber) and should be fine if properly lubricated. i replaced the rear track bar bushings on my 72 burb c20 (CPP has the larger ones for the 3/4 ton track bar). planning to get their poly graphite body mount bushings as mine are rotted and i don't want to spend lots of money on rubber. looking for (extreme) long term durability as my truck gets nothing but the best and i'm not worried about a little squeaking (no helping that on a 38 year old truck anyway).
