DT-03 Rear Lower Arm Upgrade

This aluminum rear lower suspension arm is an RC-scale replacement part made for the TAMIYA DT-03 chassis. Produced as a direct aftermarket aluminium substitute for the stock plastic arm, it gives a firmer rear mounting point for improved suspension consistency and is intended for hobby use only.

Fitment is specific to the DT-03 rear lower location and uses the chassis' existing mounting geometry and fasteners. Installation follows standard arm removal and refit steps; no special tools are required beyond common hobby hex drivers and screwdrivers.

Specifications

  • Item: Rear lower suspension arm (rear lower arm)
  • Material: Aluminum
  • Model Number: JR-DT301-BK
  • Compatibility: TAMIYA DT-03 chassis

Fit this arm to reduce flex and increase durability at the rear lower mount when dialling in DT-03 suspension setups for track days or routine hobby maintenance.

Will this fit every DT-03 rear lower layout?

It fits the standard DT-03 rear lower arm position. Confirm your variant uses the common DT-03 rear geometry before installation.

Do I need different screws to install it?

Most builds reuse the chassis' existing hardware. Check that the current fasteners seat correctly and swap any worn screws if needed.

How does aluminum affect handling compared with plastic?

Aluminum reduces flex relative to injection-molded plastic and helps maintain more consistent suspension geometry under load, which supports repeatable setup changes.

Is this suitable for on-track use?

Yes. The arm is intended as an RC-scale component for hobby track and recreational use with the DT-03 chassis.
