Urethane Bushings on 1st Gen

Bmanxer · 06-29-2008, 07:30 AM

Any of ya'll done it? I couldn't find any write ups or how-to's on it. I was thinkin about doin one when I got home if nobody has made one. If you have done it, what'd your truck feel like after?

I ordered the prothane kit that ALSO includes trans mount and body mounts on top of the suspension bushings.

Any experience/info is appreciated. Much thanks!

bg's · 06-29-2008, 09:12 AM

I put poly motor mounts in my ride and the vibration
at idle even after a couple years irritates me a lot.
I can't even imagine what it would be like at idle
with a poly trans mount installed as well. If I ever
have to replace the mounts, I'm going back to
rubber or some from JTR.

A lot of guys don't mind the vibration after installing
poly. Not so with me. Just my 0.02

Project89 · 06-29-2008, 10:10 AM

Think that is bad , I had solid motor mounts on a mustang with a strocker motor . Vibrate your teeth loose .lol

Mystic_Knight · 06-29-2008, 10:51 AM

Ya, keep the poly to suspension parts unless you're racing or something. Rubber for engine, trans, and body mounts. I have them on all my links and front sway.

Was it a big difference in your handling? Or was it just kinda moderate? OH btw knight I really appreciate all the donating to charities and everything you do man, gives all of us a really good name, hope to do it someday w/ my truck in shows and stuff, you're an inspiration!

I like poly for everything. I had the complete kit on my old s-10 with the v8 and while its not gonna turn it into a canyon carver by those alone its a good start. I plan on getting a kit and swapping everything over on my blazer later on down the line.

Awesome! What about those combined with the 3/4" deluxe drop from western chassis (3" drop leafs with 1" drop block) (2" spindles, 1" springs) with 4 nitro shocks? I want this thing to handle confidently...

MadMikeZ28 · 06-29-2008, 04:24 PM

I do only the tranny mount in my Camaro. Its not bad on vibrations but you do notice the difference. But on the thrid gens with the torque arm they are a must unless you want to change the rubber one often. But as I assumed this thread has to do with the suspension bushings.
I used PST graphite bushings in a 84 Camaro I had. It also had KYB struts and shocks and Kuhmo high performance tires. That thing hung corners like it was a nascar! It was great in the handleing department....When the road did not have potholes! Hit a pothole and it would send you into the next lane. It was a Z28 so it had very stiff springs to start. I could not get the car to bounce by pushing on it. Its like it had no suspension travel at all. The thick sidewall kuhmos did not help either. It was bad when I take a corner hard and hit a hole or a bump in the road because the car would send me in another direction and I would have to correct real fast. But on a smooth road they are great for handling. Makes it more responsive.

im gonna guess you had non stock wheels on it.... sounds like a bad offset

MadMikeZ28 · 06-29-2008, 04:43 PM

They were Iroc wheels and the car was aligned correct. If you have no deflection then its going to bounce you around when you hit bumps and hole. Like a gocart without suspension

hellz yeah! Confident handling results in confident driving results in confident speeding

TCossuto · 06-30-2008, 10:06 AM

= bigass crash that makes me wait in traffik on the way to work

I put all urethane busings on my 2nd gen BMW (we don't say gens thou.... so e30 for anyone that knows). As the dude said above with kuhmo tires on it that mofo was like a gokart. It would WHOOP THAT ASS on corners and held its own going straight. How I ended up loosing that for this s10 I still have no idea

. The body is unibody though, so I never did bushings on it (lol) but vibrations were not noticeably different from stock to poly bushings on the suspension.

Bmanxer · 06-30-2008, 10:19 AM

Good cuz I want it to still be "comfy" (that's a sliding scale i think) but not constant vibrations...and noooo i wont make you late for work

wow thats so far off from correct information i dont know where to start.
F1 cars have as close to zero deflection as pretty much possible and they have suspension that actually works over the bumps.

So F1 suspension and chassis is compairable to a S10

85smallblock · 06-30-2008, 03:58 PM

my truck stiffened up like crazy!!! I havent been able to put the leaf bughings in but holy smokes......with my 5/6 and beltech sway it handles like its on rails.

Now THIS is what I was lookin for real world experience! Ok bro so what about your everyday ride comfort wise, what's it like compared to stock (which I'm assuming your truck is an 85 means stock in 2008 AINT MUCH) What else did you replace suspension wise when you put in your urethane bushings?

85smallblock · 06-30-2008, 04:19 PM

the truck rides stiff no lie but I basicaly have a 5-6. front beltech bar. poly body mounts and lower control arm mounts. Im going with tubular uppers I think and I didnt want to mess my alignment up.

I didnt put in the spring bushings but they will get thrown in when I get some caltrachs

MadMikeZ28 · 06-30-2008, 04:35 PM

You could also weld plates on to box in your lower control arms. Just don't forget a hole with a tube in it for the sway bar bolt.

i put some poly sway bar links, made quite a difference. i could tell there was a ton less body roll during corners

87wildside · 07-01-2008, 06:20 AM

Poly bushings bind and change your spring rate. They squeak like a bish too. They do offer a good improvement over stock however. The body mounts made a huge difference on my truck. After the full poly upgrade and Hellwig front bar on a 5-6, body roll was next to nothing.

they bind, but from what ive read, for the price, they are hard to beat
they are definitly superior to rubber in racing conditions.
until you start using flexures you will have sticktion and all these other frictional forces its hard to justify not using poly just because of bind.
as for squeeking...... ignore it lol
