Im looking at buying a set of used arp studs and am wondering is there any reason to buy new over used ? do they stretch and fatigue or any thing like that?

 

they do stretch which is why you have to retorque a few times

 

after being installed once and reinstalling am I taking a chance on one snapping on me or will they be fine just all ready stretched

 

The problem with use ones is, you don't know how much the last guy pulled them down to. If they didn't over torque them, then their fine. If some one cranked them down way pass specs, then I would stay away from them. Poeple that have studs don't replace them every time they pull their head.

 

i'd buy haisleys or someone else's before i'd buy arp. i had two brand new ones snap on me. or get teh larger 14mm ? ones and not worry about it.
