Hey guys. I need some advice on upping the hauling capacity of my rear axle. It's a 94 Chevy 30 series cutaway cube van. This friggin thing has a load on it and it is empty! Building up the springs is already planned but with the hellacious liftgate this has on it, I'm thinking about swapping to a D80 axle along with 19.5 wheels with lo profile tires. I wanted to put a hidden wheel lift on the truck too so obviously I have to do more than just the springs. Do you have any advice which D80 would suit the job best?
