There are stronger axles than Moser Engineering out there, but for your application a set of ME 35 spline will be stronger than the rest of your rear. But that will require changing the carrier to get 35 splines. If you are keeping the lesser strength splines, buy the cheapest (new) axles you can since the spline will be weak.
