TAMIYA DB-01 Reinforced Aluminium Differential Shaft DB01-05/HD by 3Racing  [DB01-05/HD]

Item summary

This aluminium differential shaft is an aftermarket hop-up designed for use on DB-01 based models. Supplied as part DB01-05/HD, it is a heavier duty substitute for the standard shaft intended to better sustain drivetrain loads seen in performance driving and setup experimentation.

Fit and compatibility: suitable for DB-01 chassis variants that accept the DB-01 differential shaft, the component replaces the factory shaft at the same mounting points and performs the same core role within the differential assembly.

Installation and tuning notes: fitting the shaft follows standard replacement steps - open the differential housing, remove the original shaft and fit the aluminium spare, confirming correct alignment and clearance. As a tuning part it raises structural stiffness in the diff and aids geometry retention under elevated loads, which can help maintain consistent throttle response and corner exits.

Material and maintenance: made from aluminium to improve abrasion resistance versus softer stock materials; regular inspection of splines and contact zones and appropriate lubrication will help preserve service life. Follow normal RC maintenance routines when working on the differential.
