ARRMA Kraton 1/5 8S 53T Steel Center Differential Gear by GPM MAKX053TS  [MAKX053TS]

Center differential gear for ARRMA 1/5 8S

This GPM MAKX053TS center differential gear is an RC-scale replacement part engineered for ARRMA 1/5 8S platforms. The unit is a 53-tooth, 1.0 module center diff gear manufactured in 20CrMnTi steel, intended to restore or increase drivetrain durability where the factory gear has worn or failed.

The tooth count and 1.0 module profile match original ARRMA geometry, and the hardened 20CrMnTi steel construction targets longer life under heavy brushless setups. 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. Use existing internal diff components and follow your chassis service practices for grease selection and preload; this gear serves as a wear-resistant component rather than a tuning item to change diff behavior.

This steel 53T center diff gear is a direct, RC-scale replacement to maintain drivetrain strength on ARRMA 1/5 8S vehicles, suited to heavy brushless use where durability is a priority.
