Centre Differential Gear Set for ARRMA 1/5 Vehicles

This RC-scale centre differential gear set is manufactured from 20CrMnTi steel and contains a 36-tooth centre gear plus a 12-tooth idler gear, both 1.5 module. It is provided as a direct replacement for factory parts ARA310919 and ARA310921 and is intended for ARRMA 1/5 Kraton and Outcast platforms listed below. The parts are chosen to deliver improved resistance to wear in typical RC drivetrain service.

Fit this set when restoring or reinforcing the centre differential to regain correct gear engagement and drivetrain behaviour after wear or impact. The gears are made for standard installation into the existing centre diff assembly; always confirm gear alignment, backing plates and bearing condition while replacing components to ensure dependable operation.

  • Center Diff Gear 36T Mod 1.5 - 1pcs
  • Idler Gear 12T Mod 1.5 - 1pcs

Intended as a material upgrade to the ARRMA 1/5 centre differential gears, this set provides a like-for-like fit for the models shown and aims to restore drivetrain durability without altering the original assembly layout.

Are any modifications required to fit these gears?

No layout modifications are expected; the set replaces ARA310919 and ARA310921 and fits the original centre diff assembly, but confirm mesh and bearing condition during installation.

How does the harder steel affect long-term durability?

Harder 20CrMnTi steel improves resistance to wear and pitting under stress, which can extend service intervals for the centre diff gears compared with softer stock materials.

Should I replace other diff components at the same time?

While not strictly required, inspect and, where necessary, replace worn bearings, shims and seals when fitting the new gears to ensure correct mesh and longevity.

Which exact ARRMA references does this cover?

Compatibility details are provided above and include several Kraton and Outcast references such as RTR-ARA110002, ARA5810, ARA5208, ARA5808V2, ARA5210 and ARA5810V2.
