Hi All,

I found out both of the rear coil springs on my cobalt are broken, and judging by the rust on the tips where they snapped, they've been broken for a while. Suprisingly, it doesn't look like the back end is all that much lower, probably because I've only lost one turn of the spring...maybe a turn and a half.

Replacement doesn't seem too hard, but I'm seeing a few different options for a basic replacement coil. My question: Is there really any difference between them?

OEM coil is SPRING | Genuine GM | 22705489

ACDelco 45H3154 Amazon.com: ACDelco 45H3154 Professional Rear Coil Spring Set: Automotive

Moog CC81065 http://amzn.com/B004991LRE

Prices vary depending on where you find them online, but in general I'm seeing Moog as the cheapest.

Any thoughts?

Buy directly from the dealership and get the FE5 rear springs. They're dirt cheap ($100 for two) and the handling difference is night and day.

I'm not really worried about upgrading the springs from FE1 to FE5, I just want to swap out the broken ones. I plan on going to the cheapest route now (Moog) and my question is, is there really a difference? When I say difference, I'm talking dimensionally. I'm worried the moogs or acdelcos are going to be slightly shorter/longer/fatter and throw a wrench into the replace process.

It has 125k miles on it and (hopefully) I won't be driving it a year from now. So even if the moogs only lasted 30-40k miles, at the point it's not my problem anymore.

Not to be a dick, but I'd take money_man up on his suggestion and seriously go for the FE5 (2008-2010) shocks/springs on all four corners. They were tuned and developed on the Nurburgring whereas the stock FE1s are absolutely horrible for anything short of off roading, plus they're quite often cheaper, so it's a no-brainer decision. That's what I did (kinda) when my rear springs snapped like yours on my '06 G5. The drop is negligible and the car really wakes up and turns on a dime. For the little coin you'd spend, you will not regret it.

To directly answer your question, no, all the springs will fit no problem at all. Although I would do what I said because it's night and day better

That Amazon listing looks like it's for 1 spring btw.

The MOOG replacement spring is meant for several vehicles, although they do fit, they are not a perfect fit. The first few rows of the spring often rub together and pretty soon the have the squeaky school bus sound. ( Very annoying ). I went with the FE5 rear spring because they were cheaper for a pair and don't regret it at all. FE5 on the right.
