The mod for the rear springs is steel main leafs which if I just wanted the OEM update it can be done by swapping out the front hangers and using 1996 Astro or later springs.With this van I am going to a custom spring set-up.A steel main leaf and secondary springs with center holes that shift them more towards the front than the rear.Mopar used to call them Super Stock springs.When torque is applied it act like a traction bar lifting up the body.

I am going to do a 3" front and rear lift.I will go into more detail on that in a little bit.We are doing that for a tire size increase to 29".Rear end is going to be a Ford 9" build by a outfit near Syr,NY.
