I was thinking about upgrading my rear control arms. It appears Spohn may be the only ones who make them for these trucks? I don’t really need any adjustment because my truck isn’t lowered that much but for the one arm that’s the only option. I was just curious if there was another brand a didn’t find in my searching. I’m trying to decide if it’s worth the money over buying new GM stuff, I don’t have a supercharger so I don’t know if it’s even necessary.
Spohn the only one for upgraded rear control arms?

I couldn't find any other options either. Ended up with Spohns boxed lowers because I didn't want the spherical joints or adjustability. Haven't found any good uppers either but I am working on a set of custom adjustable uppers.

I plan to extend and box some new stock lowers and make my own adjustable uppers. The noise and harshness of spherical joints just isn't necessary unless you're at the track trying to hook 1,000 HP at the wheels.

Box in the original lowers.
I still haven’t found uppers. Here are the boxed lowers I am using. The only thing I want to do is tap them for grease zerks.

My spohn boxed lowers are tapped for zeros and were under $200 if I remember right. I'll try to find a link to them as ai don't see them with a quick Google searxh anymore.
