b4 ordering the flm hybrids i opened the rear diff to see wats the prob turns out its not the gear that stripped , its the case that somehow broke , the place the holds the spider gears and shaft in place in the gear carrier broke , so i went and i bought another gear case and the same problem happened again during the first run , should i get the aluminum gear carrier?? will it fix my problem? or is the flm hybrids the only way to fix the diff problem im having??

just to be sure , the new 3905 hybrid bulks uses 1/8 diffsto , right??

or will the 3906 hybrids fit in the 3905 e maxx ?


decided to get the 3906 hybrids since in the description of the new one is written stock replacement

All maxx parts are interchangeable when it comes to front and rear ends, so the hybrids would indeed be the best option by far- alloy diff cups and cases wont fix the weak ring, pinion and spider gears of traxxas diffs. You will also need to get the hotbodies 1/8 scale buggy diffs and pinion gears that Mike sells, or look for Ofna 1/8 diffs as an alternative; some 8x10x0.5mm shims/washers will also be required.
