It all comes down to the quality of the internals. I bought a set of the all metal SCX10 style axles and ran them on a Wraith. I broke 3 CVD's and one rear axle internally before swapping out for genuine SCX10 axles. You also need to thread lock every nut and bolt or you'll found half will have shed by the end of a session.
They're OK, portal gears are pins not squared off like TRX4 but TRX4 portal gears often crack as a result. I'm going to run them and see what happens. The ring and pinions are no different from stock axial stuff
Hey man, i know im a little late to the party lol but thats a cool truck and axles to!! Do you happen to know if those axle guts will interchange with axial ar60 guts?
