how much can the stock driveshaft take? with that what would be a good oen to swap to? would a GT one fit and be stronger? or should buy an aftermarket one? is it really crucial for a N/a stang to upgrade this? i occasionaly have hit up to 110 but very rare. any input is appreciated.

and on that note how difficult is it to do? could i do it myself? or does it have to be installed. thank you

 

Depends on the year. The 2005 and early 2006 driveshafts lacked retaining clips and are unsafe at high speed (>110). The later ones have the clips and can handle what you are dishing out. The GT one will not fit and and is also a heavy POS. I wouldn't bother with upgrading your driveshaft from your description of your car and driving habits.It isnot that difficult of a job but I wouldn't recommend it in your case.

 

ok thank you i have been reading alot about the driveshafts breaking and got worried but no one mentioned the year i have a 2006 that is an end of the model year. thank you for your help

the newer oneswith the clips what can they take? how much better are they?

 

It's heavy and overly complicated for a driveshaft but it'shighly unlikely to break especially the way your driving habits are.
What happened (in a very few cases) is that at high speed/high rpm, the lack of retaining pins was causing the u-joint to slip out due to vibration. When that happened the driveshaft end dropped and hit the ground at high rpm causing it to break.
