I am looking to increase the diameter of my rear sway bar on my 2007 SS 5.3 L, would like to purchase one from someone. Currently the one on the car is 18 mm (11/16") in diameter and is solid. Would like to bump that up to a solid 24/25 mm (prox. 1"). Does anyone know of anyone who sells them or makes them up special order. Any help would be appreciated. Thank you. S. Buscemi I have tried BMR and they do not make one bigger than 18 mm as I have been told.

I know those are stabilizer bars and not sway bars, but you may want to look at them as well.

 

Rick: Thank you, I have these exact bars on my car and I have changed out the front sway bar with a GMPP upgrade. It is the back sway bar I am having difficulty finding an upgrade for. If you know of any info on that upgrade I would really appreciate it. Thank you for your help. SAM

 

did you ever find what you were looking for? i think there is a gmpp rear sway bar as well at least there is for the 00-05s

 

Kind of off topic here, but do sway bars actually add that much of a noticeable difference in handling? I thought struts did that more than sway bars.
