9c1fast

I have an 06 9c1 impala.I'm looking to up grade.I think the the 9c1 has the larger sway bars but I was thinking GM might have larger ones or maybe Addco? Thanks

your front sway bar is 20mm solid. if you want bigger and badder dorman makes a kit of a direct fit 33mm solid one. your rear is a FE3 (SS) sway bar and i have not been able to find a bigger one for the back yet. best bet would probably be Strut tower bars front and rear with the dorman replacement front one

Awsome.Thanks for the info.I recently saw the Dorman sway bars on E-Bay.

+1 for the strut tower brace bars . They make a big difference.

Got the strut tower braces just waiting on the brackets.

I emailed Addco about their sway bars and I am waiting to hear back from them. As soon as I do I can post their answer with part numbers.

Where did you locate the strut tower brace. Is there a manufacturer and is it just a bolt on or do you have to drill holes etc. ?

I looked around on the web, google etc. and could not seem to locate one. There are kits that you have drill holes etc but prefer a bolt on if there is such an animal

Thanks

Get some brackets from Don Rome for the STB. Home Page

The reply I got from Addco is that 740 (front) 639 (rear) will fit my 2012 (from 98-12). I had the same ones on my GTP and they were awesome! I'll be ordering some in a few weeks.

For what car? There was no impala in 98, or 99...

I think he means the pontiac grand prix's sway bars will fit the impala up to 2012. Pontiac's W body car from 1998.

sorry for the confusion....
And thanks for pointing that out! I was looking at the Addco catalog and they list from 98-10 for the 740 front and 639 rear bars. (I guess that should be 99-10 since production did not start until 99? )

My GTP was a 98' and I didn't get the bars until about 2008. I should write to Addco again and ask them to update their catalog. Unless the 'MIB' have the 98' aka Prototypes! Watch out for the guys in black.

Here is the catalog After Market about Anti-Sway Bars ADDCO

I have an '06 LT 3.9 and will be upgrading both sway bars. Check out www.newgmparts.com/Accessories/GM Performance parts/Chassis, Suspension & Brakes/W-Body. They have a 34mm front and a 19mm rear with decent prices and they come with bushings.
