Boxer trans shaft same as the Tr with same weakness

The TRs are known for having a weak trans shaft that can break under load, the one from my Boxer looks fairly small and weak also,the upgrade is to use a 512TR shaft, do Boxers suffer the same issue with them and can you upgrade to the 512 shaft?

Thanks

Jeff,

I have heard of 1 or 2 Boxer shafts breaking, but I certianly wouldn't call it common. The TR's are quite a bit heavier and have much wider rubber which when used to the extreme puts far more load on the shaft than a Boxer. As far as retro fitting, never tried it.

Thanks JR

When they broke did it damage the case/bellhousing?

Hi Jeff,

no the case doesn't get damaged if the shaft breaks.

Hi........

Please clarify.....to which "trans shaft" do you refer in this thread ??

Frank,

the actual "drive shaft" that goes from the lower transfer gear to the trans.

not really a big issue, but as mentioned they have on occasion been known to snap.
