Tamiya TA05 chassis aluminium differential shaft by 3Racing TA05-19/LB  [TA05-19/LB]

Aluminium differential shaft for TA05 series

The 3Racing TA05-19/LB is an aluminium differential shaft designed for use in Tamiya TA05 family 1/10 scale touring car models. As a drivetrain replacement part, it is intended to replace the factory steel shaft with a machined aluminium unit to offer a balance of weight and stiffness appropriate for track tuning and maintenance.

Fitment covers the TA05, TA05-IFS and TA05-R variants as referenced in the product name. The shaft works as an internal component of the differential assembly and interfaces with the existing gears and bearings on those chassis; confirm clearance in your differential housing before installation.

Installation notes: remove the differential carrier according to your chassis manual, service the internal gears and bearings, then replace the shaft while observing gear mesh and bearing preload. No specialised tools are required beyond typical model workshop items such as hex drivers and a small torque driver; inspect parts for burrs and clean lubricant paths after assembly.

Tuning role: swapping to an aluminium shaft can alter rotational inertia and perceived feedback from the differential during acceleration and deceleration, which some drivers use as part of overall drivetrain setup when adjusting gear ratios, spur/pinion choices, or diff lubrication levels.
