how well do the stock axles hold up on an 03 cobra?

 

I have a 99 and mine is holding up pretty good. I have heard if you are at the dragstrip with sticky's and launch really hard you will snap it.

 

not so good unless you have all the suspension upgrades ie. bushings subframe conectors diff brace etc.. otherwise depending on you power you could snap your half shafts. i actually am in the process of getting my diff cover replaced because i cracked it the other day.
