GM 25821162? That seems to be the preferred Cobalt swap.. NLA from everywhere that I've searched.

 

That one the other number shows non SS

 

Yep.. uh-oh...

 

The older the HHR gets the harder to fine parts , and the Cobalts are not any easier to find parts for either

 

Yeah.. sort of sucks to have that built in obsolescence. I found a MOOG set ( ) that is theoretically the direct replacement for the Cobalt SS springs. For the price it's worth the look-into. Supposed to be crap weather and cold this next week so I don't know when I'll get to install them.

Post pictures if you decide to get them. And part numbers

 

Wow letterman7, those rear springs look terrible with those dead coils. Looks like all your suspension travel/load is being put on 1 single coil. Not a very good design.
Guess I was lucky to get my rear Pedders prototype springs. They were apparently a one of a kind because they never were produced after I trial tested them for Pedders. 1.5 inches of rear drop and still working good after 8 years.
Picture from when I installed them.

 

Aw , Pedders, I thought those were Canuck Motorsports

 

Yeah, I wasn't happy when I put the car back on the ground. I have MOOGs coming in from Amazon, probably tomorrow, but it'll be a bit before I get them installed. I don't have to go anywhere, so the car can sit.

 

Yep, I have the Cobalt SS/TC rear springs. GM part number for the SS/TC rear spring is # 25621162 for both sides. 1 1/4" drop

And I do a lot of hauling w/no issues.. You say they are NLA ? Hard to believe. Rock auto has Moog for the SS/TC. or Ebay ?
