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.
