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

Compact shaft summary

This aluminium differential shaft is an RC-scale hop-up created for compatibility with the DB-01 platform. Sold under part DB01-05/HD, the unit provides a heavier duty alternative to standard shafts to better cope with increased drivetrain stresses encountered during aggressive driving and setup changes.

Fit and compatibility: intended for DB-01 chassis revisions that accept the standard DB-01 differential shaft, this part fits the same installation location and functions as the original shaft while offering increased structural resistance under load.

Installation and tuning role: installation follows the usual steps for replacing a differential shaft - access the differential housing, remove the original shaft, fit the new aluminium shaft and check alignment and clearances. As a tuning upgrade, the shaft raises rigidity in the differential assembly and helps stabilise geometry under higher loads, which can improve repeatable power transfer on acceleration and corner exits.

Material and maintenance: manufactured from aluminium to improve wear resistance compared with softer materials, the shaft benefits from routine inspection at splines and contact points and from light lubrication where applicable. Follow standard RC maintenance practices when servicing the differential to extend component life.
