not having a prob in that are, just the internal diff mesh. But thanks for the suggestion.
On the motor, it depends on what tires your going to be running and how much bite your track has.
My 8.5 is easily contrllable with aftermarket tires. i almost want something even hotter, but don't think the truck wants to hold more than an 8.5, although the track would.
I think if you get a 17.5 or 13.5 you will be dissapointed and end up wanting a new motor. if in doubt, buy the hotter of the 2 your in-between on and gear down opr turn down your epa if need be. Then you have it if you need it without spending another 90 bucks. JMO!!!
