Hard-anodized 7075 differential case and idler gear

This aftermarket differential case and idler gear set replaces ARRMA part ARA311095 and is built for ARRMA 1/10 monster and stadium platforms. The parts are CNC-machined from 7075-T6 aluminum and finished with a hard anodize to provide wear resistance and stable gear engagement under hobby driving loads. It is intended as a direct-fit substitute where the same mounting points and 0.8M gear pitch are used.

The kit prioritizes gearbox longevity and consistent mesh rather than altering gear ratios. In tuning practice the assembly reduces wear during heavy use and gives a more stable base for adjustments elsewhere in the drivetrain. Fitment follows the vehicle differential layout and uses the supplied bearings and fasteners to put the unit back together. Reference code MGO1200A is supplied for ordering and service queries.

How does this affect drivetrain tuning?

The set maintains original gear ratios and pitch while offering a firmer mounting base, which can stabilise mesh and allow more predictable tuning of slipper and diff settings.

Is model MGO1200A compatible with Vorteks models?

Yes, the listed compatibility includes Vorteks 2WD stadium truck models that use the same mounting interfaces and 0.8M gear pitch.

What maintenance benefits should I expect?

Expect reduced wear at the gear mesh and longer service intervals under comparable running conditions due to the stronger 7075 alloy and protective anodize.

Do I need extra parts to install?

No additional parts should be necessary; the kit includes the bearings and Grade 12.9 screws required to reassemble the differential.

Where can I find the part reference?

Use reference MGO1200A when ordering or referencing this hard-anodized 7075 diff case and idler gear set.
