GM SPO shocks do not come with ZOK springs.
I removed the GMPP springs and replaced them with the ZOK springs. Same Spring rate, but about 1/2" lower.

Ah, that all makes sense now. I was thinking, these look lower than the normal GMPP setup.
Fronts were easy since they are accessible from the engine bay. Will check on the rears later this week. They seem silent, and I need the car tomorrow afternoon, so I'll get to them Thursday.
BTW, a weird thing happened to me the other day. I went into my trunk to get my compressor. I power it off a booster pack with a 12V cigarette lighter outlet to pump up my mountain bike tires. When I pulled it out of the trunk, I noticed that there was some off white to off white stuff int he clear tube that the sealant comes out from.
I've used this compressor MANY times now (I adjust tire pressure weekly, and use it on my mountain bike, etc) and have never had an issue with it. I know I put it back without this problem. So unless the pump managed to power itself up in my trunk, I'm going to say it leaked. The only thing I can think of is, it's been REALLY hot the last couple weeks. Many days in the high 30* C, and over 40* C with the humidity, let alone how hot it can get with a black car in the sun. But I dunno. Can't really explain it. Good thing it didn't leak too badly. Most of it was contained within the foam mount, and peeled off easily.
Just thought I'd send out a little "check your sealant" reminder. I've always kept a can of extra sealant (higher quality, and guaranteed not to freeze) and a proper patch kit with the vulcanizing patch strips in my car anyways. I'd hate to actually use the injected sealant, so I've decided I will only keep the compressor and the patch kit in my car now, without the sealant of any kind.
