Hey you guys Im having a little trouble finding the thread about the rear suspension upgrades for the 06+ SS's . i know that our cars have trailing arms that are on a offset but dont remember what vendor offered an upgrade.
Im almost 100 percent it was UMI but dont remember. believe BMR offered thicker arms that rubbed and i think UMI had a slighter offset that worked. this is off the top of my head so i could be off. but if you guys know or have them installed please drop in. comments are always welcomed.

Hello,
I have heard of other brands using larger diameter tubing which lead to tire rubbing with wider tires. We use 1.250" DOM tubing which is not larger than the factory arms and we haven't had any tire clearance issues.
If I can help anymore please ask. Also this item is on sale right now too![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Thank you!

Well the 06+ SS's got the "updated" parts although some are kinda one off" the sways are bigger. Struts are different at least in tha rear.trailing arms are rectangular and on an offset I believe on the LTZ and SS .

Guys on the other w-body forums used to use the GMPP trailing arms as an upgrade to the factory parts. They have been discontinued by GM. So UMI's or GXP traling arms have been talked about. It is said that the GXP trailing arms are the same as the GMPP one's. Plus the GXP's are much cheaper than both.
