nice...I have GF kit on my truck, very nice quality.

how much drop does it give and part #?

PM will be sent

Thanks, please let me know how the install goes and if there are any issues. I look forward to the pics

Got my springs installed late last nite. My buddy came over & didn't leave until 11:00 PM:roll:. This delayed the project so I started kind of late. Got out into the garage about 11:15pm & finished around 12:30AM. This install took a little longer than usual because I had to take pictures for all my HHR.net buddies:D. This was distracting at times. Remove a bolt, stop take a picture. Should I take a picture of this? What, my camera needs batteries? haha Overall I would say this was a pretty easy install (for me). I broke a sweat but that may have been the 90 degree heat & camera stress haha. I measured the stock height:

The kit comes with full instructions & I advise you to read & follow only those directions. I am merely posting my install experience for my fellow HHR brothers & sisters. I started by jacking up the rear end so I could remove the wheels. I followed the HHR owner's manual instructions. I set the parking brake & put wheel chocks under the front tires. I used jack stands to secure the vehicle. I removed the wheels.

I then loosened & removed the 10mm nuts that hold the brake line in place. This will allow the suspension arm to rotate down all the way & not damage up the brake line.

I put a jack under each suspension arm to support it while I remove the bottom shock bolts. The instructions note that the arm could 'spring out' quickly when the shock bolt is removed. It didn't happen to me but be careful! I used the lug nut wrench to remove the shock bolts.

With the shock bolts out I was able to lower the whole rear suspension arm with the jacks. I then grabbed the spring & wrestled it out. They were in there tight because of dirt & crustification but I was able to 'pop' them out by grabbing the spring with both hands & using a twisting motion.

I then removed the top & bottom plastic pieces from each stock spring, cleaned said pieces & re-installed them into my shiny-new Ground Control springs.

Note the 1" difference in (free) spring length.

There is a note to install the rear springs with Ground Force logo 'up'. These are ready to go!

Re-installing the springs was easier because they are shorter. Jacks under the suspension & re-install the lower shock bolts. Re-install the 10mm brake line nuts.

Re-install the wheels.

Road test. I could feel the lower stance right away. It wasn't 'squatting' in the rear, just level:D

Hanlding on my quick around the block road test revealed a new handling feel. With the rear end high, it tended to turn-in easier (maybe too easy). Know it tends to 'drive through' the turn instead of falling into & out of it.

Before & after pics will be posted soon!

This picture is a little dark. I'll post more later:

Looks good. Nice work. Very Nice how to.:thumb:

sweet....thanks for the detailed pics, gonna make my install alot easier now.

It's better than stock, but I would find it hard to justify such a small change.

Also, they've been using that same box design for years lol.

I think its a great mod, just like fullsize trucks adding rear drop shackles to level them out...gets rid of that stinkbug look...lol

Nice work and nice write-up, HHR_style...

Question for you. After you have driven it for a while, notice if you have a thump when you have a rough road. SOME owners have indicated they needed to cut the rubber bumpers to prevent this from happening. Although I think all of them installed the Goldline springs.

Just wondering if Gound Force provides a little more engineering in their product, for the HHR (I also had them in another vehicle, and liked them very well).

I may want to get these now....I'm out of warranty.

looking at the pics and stock shocks, just wondering if anyone has upgraded to a better shock.

I've had my GF's for about a year now, and so far I've had no thumping on rough roads or the occasional speed bump.

No 'thumping' & thanks for all the comments. I'm very happy with the result/ride. (for me) it's perfect.http://www.chevyhhr.net/gallery/files/1/5/0/9/9/installed_164455.jpg

Where can this particular brand of springs be purchased, and at what cost? I am about to order the Goldline leveling springs for my wife's HHR, but I would consider these as an alternative if the price is right...

nice job looks good i had custom srings made by a company there name is road magnet, the springs are awesome nice ride, and handles great

I need to make a decision very soon on leveling springs for my wife's ride...I take it no one knows where I can pick up a set of these if I decide to go with this brand?

Those Ground Force leveling springs may be what I am looking for. I don't like the butt-high stance of my '09. A question for all of you if I may......are any of the lowering springs the same spring RATE as the factory springs? If the spring is the same rate, but an inch shorter length, would it still ride the same? Have any of you with Ground Force springs noticed the ride after installation? Better or worse than stock? Many thanks for any advice in advance. God Bless, Marc

Many thanks for any advice in advance. God Bless, MarcMy ground force springs seemed to be about the same rate as stock. Not stiffer or rougher. It's a nice ride! Handles & looks great!

Many thanks for the firsthand experience. Has anyone compared the ride and lowering distance of these rear springs as compared to Cobalt SS rear springs? Just curious. There are a lot of experimenters out there, and I love to learn from others. No sense reinventing the wheel (or spring in this case). :-)

God Bless, Marc
