Once you add some basic handling mods such as lowering springs, upgraded struts, better tires, etc, it becomes increasingly important to consider upgrading your sway bars. As you improve the ability of your car to stick to the road, you will notice an increase in body roll (or sway/lean). This is where a stiffer/larger sway bar setup becomes beneficial. Sway bars work by distributing the upward/downward force of the car evenly from left to right, in an attempt to keep the car level (eliminate the heavy lean, or body roll while turning) the factory sway bars are sufficient for a factory suspension/tire setup, but once you change things out, they are no longer enough. This is where the larger diameter/stiffer sway bars come in, they will help keep all 4 tires planted firmly on the pavement, and drastically improve your cars handling ability.

Ours is 1.28" in diameter.

Sway bar 101: This is assuming you have a properly setup front/rear spring rate and good shocks/struts...  For example, lets say you are coming into a corner fast and want to make the turn.  If the car tends to understeer (front pushes/does not turn) you will want to increase the rear sway bar stiffness.  People generally prefer oversteer (rear swings out) in a corner in a front wheel drive car because you can always accelerate out to control the amount of oversteer.  If the car oversteers a lot, then increase the front sway bar.

 

Fits Cobalt, Ion, HHR, G5, Pursuit

I can definitely tell the difference from before I installed the rear sway bar. I would highly recommend it if you are upgrading the suspension system.

Surprised

The installation was easy, surprised how this bolt on fitted without adjustments. Small comment, I had to run an M12 tap thru the welded on nuts, the bolts got stuck on the paint in the thread of the nuts, damaging the thread a bit on the bolts. Add 4 spring washers in the future for safety

MASSIVE improvement

I drive my 09 SS daily but I like carving corners. I haven't done a lot to the suspension except OTTP control arm bushings & new stock struts and shocks. I recently installed weld in subframe connectors & I couldn't believe the difference they made. So I was researching rear sway bars as a next step to improve the loose rear end. I decided on the ZZP one because it's not as aggressive. So I thought it would be best for street. The other bars affered are too stiff for average street driving from what I gathered. A friend of mine pointed out it was on sale so I coouldn't pass it up. It took about 15 minutes to install. I used my floor jack under it to hold it up so I didn't have to fight it while I loosely bolted up one end. Then did the other side. Removed the jack & tightened it down. It literally took longer to get the car jacked up on jack stands & to get the tools out than it took to install. Once done I took the car out for a test drive on the curviest road close by. I can't believe the difference! I really didn't think that twist beam axle moved arund that much. I honestly thought the Cobalt just basically had no suspension in back other than up & down lol. I highly recommend this rear sway bar. As always shipping cost was fair & it got here quick.
