I'll have to check that out.

I'm using the HB xmember and the Calmini shackles too. I'm wondering if you could snap couple pics from the side when you get a chance just so I can look at your placement of each. I expect it'll be a little different than my frontier, which is currently SUA. I think the extra leaf is in order to stiffen it up, else my wife will be scared to drive it, and it's her wheeling truck.

I know what you mean on the DS clearance on the Xmember. I just put a set of Alcan rear springs in my Frontier and have less than 1/2" clearance now between the shaft and Xmember. I'll be notching and putting a limit strap in the center off the diff to keep it from hitting. Those springs should flex madly though.
