How many cells you plan to run and what kind of tires? The tire size makes
a difference on diff selection. If you got a 7 or 8lb truck the diffs will survive
better than with a 12 to 15lb model. Short tires or tall tires means the amount
of leverage it has over the diff. The more cells you have the more power you
have. I hope this hasn't confussed you more.
