Whats the story with it?  Yeah, ive known about them for 9 years now but they revised it and I am not really sure what the difference is.  Whats new, what do I need, etc?

[5speedz34]

Yeah me too. I know they revised it. Does anyone know where to get one? I need to get one soon!

[pat]

from what i could tell the first design was fine with stock height cars,  but some people had rubbing issues with cars lowered 2+ inches.  but some didn't.

As far as where can you get one, I know keystone carries them, Im just not sure how much they cost there ( I would figure about 150 ) I know Ill need all the brackets and such and Im almost positive that they come with the bar. Im just not sure if the ones that they have are revised or not. I need to find out cause Im going to add one when I lower the whip.

[19Cutlass94]

Actually as I found out today, you can special order them through NAPA. Im going to do this tomorrow, so Ill let you guys know price and such

[19Cutlass94]

Well I ordered the ADDCO rear sway bar from NAPA today. It was about $100 and should be in my hands in 7-10 days. Hopefully it comes will all the brackets and such needed because I need every single one of em! haha

The brackets and bushings that come with the addco sway bar DO NOT FIT SNUG. They are infact loose. You will need to get other bushings

[Blackbombshell95]

www.truckperformance.com is where I purchased my bar.

A few problems which i've encountered with the OLD BAR.

#1 With my car being lowered 2" with the ffp coilovers, my addco swaybar would rub on the center of the rear alignment arms. There was roughly 1/2" clearance between the two. So naturally any bump on the road would allow for the bar and the center of the alignment cars to meet and make a loud annoying noise.

Remedy: Air hammer to remove a little bit of metal from the center bottom of the alignment arms. Between the 2 nuts that you have to losen to adjust your rear TOE.




#2 It has been said that the bar can rub up against the strut by the bushing? I've never encountered this problem personally

Remedy:Adam makes little metal spacers that will fix the problem. Once again I have never had this problem.




#3 The center link design for the addco bars SUCK ASS. DO NOT follow the instructions that come with the addco bar for the centerlink fabbing! Doing so will only result in your center swaybar hangers snapping in half. This has not happened to me but i've seen this happen to many others.

Remedy: Use your stock center link hangers (#10259660 from www.gmpartsdirect.com). It is rumored the new version of the center swaybar hangers (#10259660) is stronger than what came from the factory.  To use your stock center bar hangers you will be required to buy this bushing/insulator from www.gmpartsdirect.com  (#10270253 X 2   (22mm)) That bushing/insulator(#10270253) will allow you to use the addco 22mm bar with your stock sized center bar hangers. And it has been recently proven(by PCGUY112887) that this will all also work with the REVISED bar.




#4 The polyurethane bushings that come with the addco kit are not snug. They are loose. My experience with the addco bushings was terrible. I had LOTS of sway/play in my steering. I would actually loose control of the car because of this issue while taking VERY hard turns at high speeds. The remedy below helped solve this problem.

Remedy: Greasible Energy Suspension Polyurethane Bushings that are of the CORRECT size. And i'm referring to the OUTER bushings. www.schucks.com 95158G X 1 (22mm).




Note on the 95158G bushings: The bushing kit(95158G) X 1 comes with 2 brackets and 2 new bushings. You will have to use the brackets that come with the new bushings. The diameter of the bracket holes that go into the lower strut bolts needs to be enlarged. The bracket holes are just a tad smaller than the bolts it's suppose to go over. Nothing that a larger drill bit or a die grinder couldn't fix.

Remember to always grease up your poly bushings.

Well thats why they revised the Old Bar, so that it wouldnt have any of those problems.


The only thing Im concerned about right now, is getting the brackets that attach to the frame rails. I have the holes there for a bar, but they are not threaded.

[Blackbombshell95]

PCGUY i think is having a clunking noise also at a stock height with his REVISED BAR.

And you have to use the bushings that I listed above for the revised bar as well.

What do you mean by frame rails?

[19Cutlass94]

I need the top bracket.




The bushings are not a problem. I can get them at work.

[Blackbombshell95]

Looks like you hacked ur stock center bar bracket in half which is the directions addco gives. How long have you had it like that?

[19Cutlass94]

I dont have the bar yet, as this isnt my car. Im just using the pics....

[Blackbombshell95]

Oh, u have a FE1 suspension

[19Cutlass94]

yeah. I have FE1 suspension, which has NO rear sway bar. I probably should mention that the car will also be lowere via FFP and ST springs
