I'm definitely looking into sway bars, but after doing some research I have a question.... From my experience, every sway bar I have seen has linked the suspension to the body to control body roll... I can't see how controlling the flex on the rear trailing arm will control body roll. If you just take the flex out of the rear, wouldn't you have to take some flex out of the front to keep the wheels on the ground?

 

There is a front sway bar already on the vehicle.. depending on which model you have, determines the size diameter of the sway bar...

 

Jim, being a 4 wheeler, I'm sure you have dealt with a few sway bars (disconnecting then!), but let me tell you - the HHR sway bar works miracles! I've installed quite a few over the years, and sometimes it is barely discernable that they do anything. On the HHR however, the difference is immediately noticeable. Less body roll in corners, less wind sway at highway speeds, heck, even a sharp lane change is improved! I'd say it is one of the top 5 mods you can do to the HHR - big benefits.

And hats off to Henry (HVROD), for finding the manufacturer!

 

Just click that grey car in my signature above Karen...

 

Very cool.... After looking at several web pages and even some cavalier/cobalt forums, I don't see any that connect to the body. So it must not need to. I'm going to try the Progress bar and see... thanks for all the info.

 

Definitely agree. The differences were night and day on the HHR.

 

On the sway bar hook up, I also have a 65 El camino,a nd added a rear sway bar. The bar justs bolts to the lower control arms (4 link susp.) using 2 bolts per side. The two bolts on each end help control the bar from twisting.
Hope this helps

 

Just received my Progress Anti-Sway Bar. The installation instructions say to jack the car up and remove the wheels, but the SoCal HHR Website says to leave the car on the ground.

Any thoughts about install preference?

I've read where alot of people have been able to crawl underneath without having to lift vehicle at all to install the swaybar. That wasn't the case for me...lol...I'm a little too big to do that 6'2" @ 235lbs. so I backed mine up on ramps. Worked out great. Took all 15 minutes. No tire removal needed.....
Regards...........

 

I'm 6' and about 230lbs and I fit :) Did it right in the driveway without taking anything off. My only problem was with my torque wrench.. it's long handled so it was a bit tricky, but it's very doable on the ground.
