Shocks for a stock height Express van?

My shocks look pretty beat up, nasty and I have a "thump" in the passenger-side rear area that is suspension related so I think it's time for some new shocks. The issue seems to be that there are not a ton of quality options listed for a 2005 Express Van AWD 1500. Here is what the mounting for my shocks look like:

Front design


Rear design


KYB and Monroe seem to the only brands out there that have my van listed. If all else fails, I'll probably go with matching KYB Gas-Adjust shocks in all 4 corners (Link).

However, I would be intested in using Bilstein but nothing is listed for a 1500 Express Van. I did some digging and Bilstein does have a HD rear shock for the Express 2500. Bilstein also has HD and 5100 series shocks available for the 1500 Avalanche which shares the same front mount design as my van but a double-eye rear design. I have confirmed that lengths are mostly correct. The gross vehicle weight of my van is 400 lbs. more than an Avalanche (7200 vs. 6800 lbs.). Many of these numbers match a Yukon XL 4x4 that has a GVW of 7200 lbs. My question and assumption is are these shocks are valved differently to the extent that they would not work in my van or is this a case that they just aren't marketing to the van segment much?

If the lengths and valving work, I found this conversion kit that I believe would convert a shock with an eye to the design shown above. Does this seem correct?

Summit Racing


Thanks for any help! If this proves to create more questions than solutions, I may just go with the KYBs. I'm just trying to think outside the box a little. Here is a detailed list (with links) of the Bilstein shocks that I'm wondering about:

Bilstein HD (B6)
Front - 24-065009 (for 2005 Avalanche 1500)
Rear - 24-025706 (for 2005 Express Van 2500)

Bilstein 5100
Front - 24-186643 (for 2005 Avalanche 1500, 0-2.5" lift)
Rear - 24-187237 (for 2005 Avalanche 1500, 0-1" lift, would need Summit Racing adapter for top mount)
