So, here's what I decided to replace it with. 4 ga Stinger Custom Pro wire. I used simple crimp connectors (although you could use the set screw type as well) to make my wires.

I also covered the wires using some techflex to give some extra protection and to dress them up a bit. The ends of the wire are covered with heat shrink.

When crimping large connectors like 4ga and 0/1, I highly recommend an impact crimper. It's going to give you a stronger connection then many of the other popular methods (bench vice, hammer and chisel, etc...) Partsexpress.com carries one by phoenix gold, but it's over $40.

I found a generic one for about $15 - great tool for this kind of work.

So here's just one of my grounds compared to what came from the factory...
