This is a locked central differential that is a drop-in fit into the original OpenRC central differential housing. I made this to help increase the strength and reliability of the drive train. NOTE: the gear itself has been modified for the same reason, and is a mod .9, so the original pinion gear (mounted on the motor shaft) is not compatible, so I've included a mod .9 version here as well. I haven't printed this yet, but I have printed a mod .9 version of the normal differential assembly and it stands up really well.
New Centre Diff printed and running great and the new gear pitch is holding up to the abuse.
By request, 0.8 Mod 57 Tooth Version added.
Recommend printing in Nylon. I use Taulman 910 for all drive train components.
