Advice on the drivetrain, okay.
Honestly i run all stock driveline parts in my truck with no issues yet but my truck was a 70,000 mile dd that now has a dozen hooks on it. I am now in the process of upgrading the driveline. Of course my tranny has all the upgrades like normal, 241dhd and a 1 piece 1480 series ujoints drive shaft. When i go to 5.13 gears, i will buy the spool and 37 spline axles from haisely for the rear d80. The front is all stock with the powertrax no slip thrown in the factory carrier. Im sure this year with the new pump and turbo that i will break some driveline parts and i will replace them as i go.
