Thanks Jason,
Differential and gears will depend on the event. Most of the time we'll be using a TrueTrac and 3.55's but at certain events we may go to 3.89's with the TrueTrac and at others we'll probably use 2.91's and an open rear.

The Axles are built by Speedway also, they are the same ones they supply to the NASCAR Teams hituff material.
31 spline at the Diff and 33 at the Hub. 35 spline are an option at the Diff also, but that does then require removing the hub to get the axle out.
Since there is a 12,000 mile warranty on them I didn't think I would have to figure that out just yet..... lol
off the top of my head i do not know the exact replacement cost on them.
Yes you will have ot get them through Speedtech.
yes the center bolt retains tha axle just so it does not move in the tube, we did this to accomidate guys who were supplying their own center sections and give more flexibility on the axle lengths with different gear ratios and diff units
