Here are a couple of pictures of the van with the new suspension from Weldtech Designs.  I had it installed in San Diego, CA when we were out there this spring (2018).  

They lifted the front 3” and the rear 1.5”.  Previously the back sat higher than the front, so the van is pretty much perfectly level now.  It is amazing how the van rides and handles. Better in every way, both on the highway and off the beaten path.
