Kyosho IF103B Differential Case for Inferno MP Series  [KY-IF103B]

Diff case for Inferno MP

The Kyosho IF103B differential case is an RC-scale replacement housing intended for the Inferno MP Series NEO 3.0 & 4.0. It serves as the structural shell that holds the internal differential gears and bearings, and is used when servicing worn internals or preparing the drivetrain for setup changes.

This part is presented as a direct spare rather than a hop-up; the description focuses on compatibility and practical workshop use. Expect the case to align with the factory mounting points and internal geometry of the specified Inferno MP Series models so that standard differential components can be refitted without modification.

Installation notes: remove the differential assembly from the gearbox or rear pod, document gear orientations and shims, transfer bearings and internal gearsets into the replacement case, and verify smooth bearing rotation and gear mesh before reinstalling. The case functions as a maintenance item during routine teardown, fault diagnosis, or when preparing the car for different oil weights and differential setups.

Tuning role: replacing the case is part of drivetrain rebuilds that support repeatable diff shimming and fluid changes, which affect traction and handling on varied track surfaces. Use the IF103B when you need to restore chassis geometry after wear or when maintaining multiple race setups for quick swaps.
