ARRMA 1/5 Kraton/Outcast 8S Center Differential Gear 53T 20CrMnTi - MAKX053TS by GPM  [MAKX053TS]

ARRMA 1/5 8S center differential replacement

The MAKX053TS center differential gear is an RC-scale replacement part engineered for ARRMA 1/5 8S platforms. The unit is a 53-tooth, M1.0 module center diff gear manufactured from 20CrMnTi steel, designed to restore or increase drivetrain durability when the factory component has worn or failed.

The tooth count and 1.0 module profile match original ARRMA geometry. The hardened 20CrMnTi steel construction provides extended service life under heavy brushless power. This part replaces the factory reference ARA310919 and is supplied as a single pcs center diff gear for direct swap into compatible ARRMA center diff assemblies.

Fitment and tuning notes: verify internal diff spacing and shim stack when installing a hardened steel gear to avoid preloading bearings or binding the diff. Reuse existing internal diff components and follow your chassis service practices for grease selection and preload; this gear functions as a wear-resistant replacement rather than a tuning element to change diff behavior.

This 53T hardened steel center diff gear is a direct replacement to maintain drivetrain strength on ARRMA 1/5 8S vehicles, ideal where durability under heavy brushless loads is the priority.
