Losi Front/Rear Differential Gear Set w/Housing & Spacers
These aren't bad, but they're not great. The internal gears all ride on plastic and as such you won't get as smooth of action as you will on a good 1/10 scale gear diff, but you also won't be losing power like you might with a ball diff that's set too loose. The problem is with the diff housing on the mini 8 and 8T these differentials have slight play between the pinion and ring gears. This is fine for stock power setups but if you bump it up you'll need to shim the diff with spacers to achieve proper gear mesh and prevent stripping. I used some trex 500pro main shaft spacers which are 8.1mm inner diameter, 12mm outer diameter, and .3mm thick. The ring gear is the weakest point and will strip before anything else, I wish I could pick them up seperately because I now have a bunch of extra internal diff gears that never really need replacing.
