Will be doing a 408 turbo/4L80E swap into the truck in my sig, and am a little concerned about front axle life. I want to still retain the 4WD, and be able to play. What would my options be? Do you think the stocker will hold up?, and if not is there anything that I can do without going to a solid axle conversion? Kinda wondering about the transfer too.

Suggestions!?

 

any help here would be apreciated.
