as we all know (when we race , plan to replace)!!!! Queation is apparently ive broke the out put shaft during a launch at the track,should i go with a stock replacement or spend the$$$$$ and go billit with both in&out shafts?Also wat is the next WEAK LINK???:duh:

I assume you didnt have a transfer case brace?

no

If you buy the input/output shafts at retail Allison Dealers (don't know about GM dealer)they are more than Billet shafts.. I would not even think about OEM,,, go with the billet.:)

After that probably Transfer case or u-joints are the weak link.

No question get the billet.

first I would suggest getting a transfer case brace. That might be why the output broke in the first place.

:)consider it done!!!! thanks
