SAS kits
 

does anyone know of anyone making kits? i tryed looking up 3leaffab.com: The Leading Leaf FAB Site on the Net and others but dead ends

3 leaf fab wnt under years ago. Offroad direct got overloaded so they ditched us. Sky sells bits and pieces but you can build your own easy enough.

It's not necessarily for your Blazer, nor am I sure if it's still available but Diversified Auto Creations has a SAS kit listed on their site for ZR2 Blazers and Pickups: Diversified Automotive Creations - SAS Lift Kit

off road direct came back with their kits i guess, but only for leaf springs, runs 290$ for front hanger, rear hangers, and shackles. however they will only sell what is already built, slowly starting up again.
