G series vans share the same suspension as C series 2wd pick ups. There are dropped spindles for the front, lowered spring, coil overs, tubular a arms...the whole thing. Rear is standard leaf springs so common options there like de-arcing or new dropped springs. It really depends on how many inches you want to drop it and what the condition of your roads are.
I had a friend who went the dropped spindle route but used g30(1 ton) springs because of their stiffer spring rate to help bottoming out. Vans put a considerable amount more weight over the front wheels and this is meant to assist with that.
Cutting your front coils is also an option, that’s a pretty cheap way to go. For my dodge I have way fewer options besides really expensive spindles and I may go the cut coil route since I’m only trying to get a 1-2” drop in the front.
Google is your friend so look through the vast catalogs for c series parts and you’ll be good to go
