D-Max Input Shaft Front & Rear - SD-303DA by Yokomo  [SD-303DA]

D-Max gearbox input shaft overview

The Yokomo SD-303DA is an RC-scale input shaft designed for the D-Max gearbox, serving the front and rear drive positions as a direct replacement to restore drivetrain continuity.

In service this shaft links the gearbox to the drivetrain; replacing it can alter gear alignment and engagement. It is a straightforward swap for the D-Max input location, making it useful during routine servicing, preventative maintenance, or when diagnosing transmission play or unusual noises.

Installation notes: ensure correct seating inside the gearbox and verify mesh and endplay after fitting, then perform limited manual rotation checks before full use. For tuning, renewing a worn input shaft can reduce slop and produce more consistent gear engagement under load, which helps predictable handling in drift and touring setups.
