This might be something you are looking for. I was thinking about the UpCountry package the other day also and was wondering if maybe the third set down in this list would be equivalent to those.

They don't list spring rate, only load capacity, and if that is true, then the UC springs would be cheaper than normal springs.

Also does anyone know if General Spring is a good company to deal with?

 

Good point, Jeb.
Wow, 13 different sets of springs? That's crazy. On my build sheet it lists me as having the "AHGP Spring Special Group" in addition to "SDAS Normal Duty Suspension", so I'm not sure what the AHGP group is exactly, but could it be that it is a softer ride?

Also, i dug up some info, and on another forum it looks like the OEM Upcountry leaves are rated at 755lbs. So id wager those are indeed for the UC.
If they are indeed a good company that makes good stuff, it might be ahead just to order two new spring packs from them for 140 bucks, as opposed to just adding a leaf.

These are the springs coded for the upcountry package branded under Crown Automotive.
