Another alternative to ramps is the one side up on the curb thing. I use the neighbors driveway as a starting point and get the ride side up on the curb and I can get under it with plenty of room.

 

Okay, the ramps make it completely easy to do this. Indeed it took me the 10 minutes the smart guys brag about. Here's a couple of added tips:

1. Ramps are key because it cures the spring sag issue AND lets you visually line up the holes. You are flying blind with the bolt plates that slide inside and under the existing spring plate holes. Also any tension is balanced with the car flat on the ramps. It's ludicrous and boneheaded that Progress says to jack the car since the springs unload.

2. So that you don't fight the weight of the sway bar hang or tether the bar to the axle bar (probably not the official term). There are plenty of holes to use. I hung a couple of C-clamps adjuster side down an facing engine forward...but you could zip tie or even use some twine or speaker wire or S-hooks. The idea here is to not fight the weight of the bar...it's pretty hefty...feels like 30-40 lbs. Anyway with it hanging/floating you can more freely move the mounting plates/holes into position.

3. Of the 2 holes on the HHR the forward hole is bigger and more movable, so mount that bolt first finger tight, then do the rear hole which will require a bit more exactness as the hole is not as big. It probably won't be a problem since the bar is not un der any opposing side forces. Conversely you could mount the forward hole on the opposing side first, but I didn't have a problem doing one side then the other. In any case remeber to leave the bolts loose so you can move the bar.

4. Working the other side like the first will still present some exactness with the final bolt on the rearward side, so with the HHR on ramps slide right under the hole under it so you can see through the hole to line up the bolt with the plate. Because you've left things loose you'll have plenty of play and forgiveness.

5. Tighten it up to 45 foot pounds... Remove any bar to axle hangers and enjoy! You can feel this mod right away, I have a 2LT Premiere Edition that has a factory bar of some sort under there but the Progress definitely adds something that is missing.

 

um, hate to say but i'm just a girl that has NO IDEA what all these mods are that you refer to so, what is a anti-sway bar, where does it go, what does it look like, what does it do (anti-sway, huh?)
heehee

 

I will send you a PM.

 

The box mine arrived in states that it is only 15 lbs. (according to UPS label).

I found this link for a sway bar for the Cobalt/HHR. Is this the correct one to purchase?

One of my concerns with my 1LT HHR is the amount of roll in the corners.

 

thats the one...

 

The stock "axle" linkage looks pretty stout. Does it really allow that much sway such that a bolt-on anti-sway bar makes a difference?

 

Surprisingly, there is a fair amount of flex in that stout looking axle linkage.

It does move quite a bit, especially in the corners...I also noticed it with crosswinds.

When I added the sway bar to my 1LT, it was instantly noticeable in both cornering and straight line driving.

 

Was wondering where you or any of you others got the sway bars. Would like to get them myself.
