New to me 2001 Suburban 2500

zachammer85 · Mar 7, 2026

Did quite a bit of work since my last post. Got the rear suspension back to stock last weekend and all the front lift stuff taken out and most of the stock suspension stuff back in. Running into an issue with the rear torsion bar mounts. The lift kit used it's own mounts. I bought what i assumed were stock replacements but I'm not sure. There appears to be some sort of mounting locations near the top of the inner frame rails but I'm not sure if those are the right mounts or not. Attached a picture of what I'm looking at near the top of the image and the mounts i bought sitting right below them.

Looks like it sits on the lower part of the frame channel (pic from charm.li)

The mounts you have there look like the ones for the pick up. My 2004 2500 uses these wishbone style mounts for the torsion key crossmember. I believe these are very similar to what the half ton pickups use. But I have not looked underneath to verify.

Most of the second half of that is speculation but this is a picture of my 2004 2500 with the wishbone style mounts that I replaced a few years ago.

If I remember correctly, my 2006 3500 DRW used those mounts you have that I believe are riveted through the frame.

Keep in mind that all of my references are for four-wheel-drive trucks I’ve never owned a 2WD so I can’t comment on what they use.
