dyno tune driveshaft cannot handle 115+

[Bikemobile]

Police package tahoe has a limiter at 120. I wonder if their driveshaft is police specific vs the standard one.

The 4WD PPV does 121, 2WD 134 per the info from the GM Fleet site.  That same site says “Propshaft, 4” Aluminum”...  I think it being a lot shorter helps it not go kaboom.
