If you are going to run 37's then I would suggest that you swap out axles if your truck is 1/2 ton. Ive seen too many people put huge tires on half ton axles then wonder why there stuff is braking all the time and not to mention the safety factor. Ive seen 12bolt axles litterally come out of rear end turning a corner. As far as driveshafts I have to switch my front to the shaft with a cv type joint at the transfer case which is gonna make it a few inches longer which I need. The rear I havent measured yet. Most places that deal with driveshafts can lengthen or shorten your esisting ones a whole lot cheaper that guying new ones. ANyway Im doing pretty much the same thing on my build so check it out. I am running one ton axles.
