I can only speak from personal experiance and on mine I was surprised that the diffs even worked with the amount of slop in them. I think that they at least should be checked to see if they need shimming. Which can be easlily done before the truck is ran for the first time.

The friend of mine that does the jumping didn't do anything to his truck other than fuel and batteries he didn't even check the screws so allot of the upgrades are dependant on how you drive. I like bigair's arms and his warranty but I'm not convinced on the need of a center diff yet myself but allot of other people are.
