The GPM DMIF100M is an aftermarket, assembled centre ball differential created for the Kyosho Mini Inferno platform. It features Delrin ball seats and is supplied as one completed assembly intended to replace the factory centre diff in housings accepting a 42T ball configuration.
This description covers installation fit, the diff's role in traction tuning, and simple upkeep notes for 1/10 buggies. The unit is designed for housings that accept a 42T ball differential layout as used on the Mini Inferno.
On track, a ball-type centre differential changes how torque is shared between axles. Delrin seating tends to lower friction and give repeatable engagement; tuners adjust grease, shim stacks and preload to shape lock up and transient response.
For model-makers seeking a straightforward Delrin-seated 42T centre ball differential for Mini Inferno, this completed unit is supplied to simplify installation and let tuners focus on grease and shim settings.
