My stock axles outlasted 3 t-5's launching 5k.

Thats in a car trapping almost 130?
I launch at least 5k everytime, have been for years, but im trapping 107 on a good day, not 120+ which takes quite a bit of power.

I say upgrade to an aftermarket 28 spline, hardened steel, or alloy's those will outlast stocker's anyday.
With 31's your looking at replacing the whole carrier, wich is fine if you have cash.....Me personally, id do it all at once with an auburn pro, or eaton posi replacement.
Later.
