Tamiya DT-03 Rear Aluminium Hub Mount JR-DT307-BK by Jazrider  [JR-DT307-BK]

Aluminium Rear Hub Mount for DT-03

This aftermarket rear hub carrier is made for the Tamiya DT-03 platform and carries the part number JR-DT307-BK. Fabricated from aluminium, the mount functions as a direct replacement to provide a metal mounting point for the rear suspension and wheel spindle area.

Typical use involves swapping the aluminium carrier into the rear hub assembly to replace the original plastic item. This upgrade is aimed at improving long-term durability in the hub area and providing a firmer mounting surface for tuning and maintenance tasks.

Fitting guidance: remove the rear wheel and associated components to access the mounting area, reuse the original DT-03 screws and spacers unless specified, and confirm bearings are seated correctly after refit. Make sure the rear suspension articulates freely with the new mount installed.

Performance impact: the stiffer aluminium pivot can reduce flex and help preserve alignment during hard cornering, which may translate into a more predictable rear-end response while tuning. Actual handling changes depend on the complete suspension setup.
