New Member, New 68 Truck, Few Questions

[long'n low]

The spindle doesn't change the geometry of the front end so it should ride exactly the same, your load capacity might be reduced with drop coils in the rear but your ride should be very similar.

At some point you need to add an adjustable track bar and relocate your rear shocks when dropping but i think 4" is fine. I'll let others chime in more about that.
