Does anyone buy used ring and pinions?

Mark,

Why are you considering going to something as steep as a 5.38 with the diesel? I would think that with 40's and the diesel's torque a 4.56 or possibly a 4.88 would be plenty of gear.

I've talked to Travis about converting my truck, Nathan at MPI about a compound setup for it and Guy at SoCal diesel about a stroker and Stage 2 heads...they've all recommended going with a 4.88 with the 41.5" Pit Bulls I plan on running.

5.38 just seems like a LOT of gear.
