Center ball diff for Mini Inferno

This GPM DMIF100M unit is an aftermarket completed center ball differential built for the Kyosho Mini Inferno platform. The assembly uses Delrin ball seats and ships as a single completed set, intended to replace the stock centre differential where a ball-type layout is required.

The article focuses on practical fit, role in tuning, and basic maintenance considerations relevant to 1/10-scale buggies. Expect the part to serve as a direct replacement for Kyosho Mini Inferno centre diff housings that accept a 42T ball differential configuration.

On track, a centre ball differential changes how drive is shared between front and rear, so this Delrin seat design is typically chosen for reduced friction and consistent engagement compared with softer materials. Adjustments to grease, shimning and preload remain the primary tuning levers when using a ball-type centre diff.

For builders who want a straightforward Delrin-seated 42T centre ball differential for Mini Inferno, this completed GPM unit provides a ready-to-install replacement intended for tuners focused on friction characteristics and centre diff behavior.
