Looks nice! Great work.
Do you have a breakdown parts list of everything that went into making this “vision a reality”?
Honestly the biggest issue for making this work is having the lower "Spring Cups" cut and extended so the air spring sits low enough on the struts.
The 2021+ struts are longer/taller overall so if you were to bolt them into a GMT900 as-is it would lift the truck.
By cutting and extending the lower cup it allows the air spring to sit lower on the GMT900 strut so you can use the proper length strut. You can see how close to the bottom they sit in this pic...
I also seriously doubt these would clear a 4wds CV axles, although with a 4x4 you could probably get away with using the longer struts as you would probably be lifting the truck anyway.
I probably have better pics somewhere but this is all I can find at the moment...
I really don't expect anyone else would go to this much trouble when there are aftermarket options available.
As for the rest of the setup:
Trailblazer SS bags out back and an Airlift 3P management system to hook it all up.
I did drill and tap the TBSS bags to allow for 1/4" push to connect fittings to be installed...
