Yokomo SD-303DA F & R Input Shaft for D-Max  [SD-303DA]

Input shaft for D-Max gearbox

The Yokomo SD-303DA is an RC-scale input shaft intended for use with the D-Max gearbox, serving as the front and rear drive input component. It is presented as a direct replacement part to restore or maintain drivetrain continuity in model cars that use the D-Max gearbox system.

In practice this shaft functions as the interface between the gearbox and the drive train; when inspected or replaced it affects gear alignment and drivetrain engagement. Technically the part is a straightforward swap item for the D-Max gearbox input position, making it useful during service, routine maintenance, or when diagnosing transmission-related play or noise.

Installation notes: confirm proper seating in the gearbox and check mesh and endplay after fitting, then run limited rotation checks before full use. For tuning considerations, replacing worn input shafts can reduce slop and contribute to more consistent gear engagement under load, which helps predictable handling in RC-scale drift or touring setups.
