Heavy-Duty Centre Diff Gears for ARRMA 1/5

This RC-scale centre differential gear set is produced from 20CrMnTi steel and includes a 36T centre gear plus a 12T idler gear, both 1.5 module. It is supplied as a direct replacement for factory parts ARA310919 and ARA310921 and is intended for ARRMA 1/5 Kraton and Outcast platforms listed below. The design focuses on strength and long-term wear resistance for demanding drivetrain use.

Use this set when rebuilding or reinforcing the centre differential to restore correct gear mesh and drivetrain behaviour after wear or impact. Install into the existing centre diff assembly and verify gear alignment, backing plates, and bearings during replacement to maintain reliable operation.

What advantages does 20CrMnTi offer over stock gears?

20CrMnTi steel provides improved hardness and wear resistance compared with common softer alloys used in some factory gears, reducing wear under heavy loads and impacts.

Do I need new bearings or shims to install this kit?

No extra items are mandated, but inspect bearings, shims, seals and backing plates and replace any worn components to ensure correct mesh and long service life.

Which ARRMA model numbers are covered by this replacement?

Compatibility is listed above and includes several 1/5 Kraton and Outcast references such as RTR-ARA110002, ARA5810, ARA5208, ARA5808V2, ARA5210, and ARA5810V2.
