The 2011 Ford Mustang — thanks to its 315 hp V6 engine — has removed the taint of six-banger econo-stangs of old. Yet more than one owner of a 2011 Mustang has has found themselves experiencing catastrophic failure with the stock two-piece driveshaft.
The problem appears to be most keenly-experienced with buyers who've disengaged the Mustang's 118 mph speed limiter. Naturally, removing the limiter likely voids the warranty.
This week another video surfaced of a Mustang blowing its shaft at around 135 mph. But that's not the only blown-shaft video that's been passed around the Mustang community. Two other Mustangs went shaft-wild, one while being dyno-tested at 162 mph.
The solution? Simple, if it turns out it's the shaft that's the problem. A heavy-duty, one-piece number like this one from Shaftmasters (no endorsement, just an example) for $625. [UPDATE: Shaftmasters has ceased production of the V6-compatible driveshaft.] Lighter, more efficient, and good for 500whp. Potential for YouTube fame? Low.
