ok circling back one more time, spoke with Lyle. He is trying to get a full kit lined up but isnt sure yet if the sway bar bushings on that super pro site are the same material as the ones he co-developed with superpro for the c4. he said he would let me know when he finds out.

im ordering a kit, and will swap over to the new sway bar bushings if they become available.

sorry for spamming this thread.

FWIW: I just bought a "full" suspension kit from Energy Suspension, and it did not come with the swaybar bushings, they had to be ordered separately by bar diameter. The swaybar bushing kits did also however come with the parts to rebuild the end links. The "full" kit did include the batwing bushings so that must be what they mean by "differential pinion bushings".
So the kit included:
1) Front control arm bushings
2) Rack mounts
3) Rear trailing arm bushings
4) Rear camber arm bushings, both early and late style
5) Rear spring bolt "cushions"
6) Batwing bushings
7) Front ball joint boots, both upper and lower
8) Two tie rod boots (additional two required for the rear toe tie rods)
I was very tempted by the Super Pro bushings but going a different way for other reasons, they look like a good solution.

Here is a list of all the parts that superpro lists for the c4.

Lyle did say that he was directly involved with development of these busings. Kudos to him!!

so here's a question, I have brand new set poly bushings for my build ('96). After reading some of these suspension threads (especially the poly bushings need to be re-greased), I just want to install and be done with it. I'm wondering if I should sell the poly set and buy these superpros?

Thoughts?

If your '96 has composite trailing arms like mine does (fiberglass tubes bonded to cast aluminum ends) and your Poly bushings are energy suspension brand, they wont work for the training arms anyway. So for those four bushings you will need to figure out a different solution..

I haven't had to re-grease my poly bushings in the front control arms, and neither did the previous owner. They've been there for years. I wouldn't worry too much about that issue. I would, however, recommend the Super Pro bushings for the rear due to bind, even if the ES poly bushings you have now will fit in the trailing arms.

Think of the front control arms like a door hinge, moves in one place, so as Mr MM (token of respect :-) says above, they should be fine for the front end. I bought Del-Alum ones to go in my car and they only go in one way.

I do wonder (and I would have to look) if grease fittings could be installed in the front A-arms themselves. Then if a good silicone based grease could be found (in a tube, or a gun that could be packed from a can), you could regrease them without disassembly. It would be as easy as greasing the ball joints are.

This is EXACTLY how the bogey wheels on my tractor are set up. In the case of my wheels, the bushings are steel. I keep them greased so the steel on steel doesn't cause abnormal wear. The prior mower deck I had suffered from this. Even greasing from the middle (2 piece poly bushings pushed in from both sides) will force grease through. It does on my tractor wheels.


As a point of interest, the Global West products have grease fittings installed in them already.

(if the following link goes away, it could be a temporary webpage, if so I will do it another way)

the above link is an enlarged view from here:

http://www.globalwest.net/1059.html

Think of the parts of the rear suspension like your wrist. Even though the primary motion is like a hinge (and like my right hand due to the injury to it) there is still radial motion. That is why harder urethane bushings bind. They don't allow that little bit of radial motion that occurs as the suspension articulates.
