The GPM DMIF100M is an aftermarket, ready-assembled centre ball differential built for the Kyosho Mini Inferno platform. Delrin ball seats are used to lower rolling contact friction and the unit is supplied complete for straightforward replacement of compatible centre diff housings.
This write-up covers practical aspects like installation fit, the centre diff's role in traction tuning, and simple maintenance notes relevant to 1/10 buggies. The unit is intended as a direct replacement in housings that accept a 42T ball diff layout.
Using a ball-type centre diff alters how drive is distributed front to rear. Delrin seats tend to give smoother engagement and predictable behaviour; fine tuning is achieved through grease choice, shim adjustment, and preload setup.
Hobbyists looking for a no-fuss Delrin-seated 42T centre ball differential for Mini Inferno will find this completed unit aims to reduce friction and simplify centre diff setup and tuning.
