I broke both a stock axle and a GCK HD axle.


Both from launching.


I agree that there is no "overall" strength difference in any of the "currently" available axles. They all are limited by the size of the splined shaft.


I recommend GCK HD axles for replacements for broken stock units because the price is good (~$125) and they carry a lifetime warranty.
