DT-03 front lower arm — precision machined

This RC-scale front lower suspension arm has been made to fit the Tamiya DT-03 chassis and carries the model designation JR-DT300-LB. Machined aluminum gives a flat, accurate mounting face that helps keep front link and hub alignment consistent on 1/10 on-road cars.

Installation follows the DT-03's original lower arm mounting points and uses the chassis' existing fasteners; ensure the arm is oriented correctly and ball joints are aligned before final torque. As a metal part it will alter the stiffness profile of the front end compared with stock composite arms, which can affect steering behaviour under load.

Designed for tuners seeking repeatable geometry and longer service life in on-road use, the arm assists with fine setup adjustments between runs. Confirm compatibility with your DT-03 variant and check the seller page for what is included in the box.

Specifications

  • Item: Front lower suspension arm
  • Material: Aluminum
  • Model Number: JR-DT300-LB
  • Compatibility: Tamiya DT-03 chassis

Use this aluminium lower arm when consistent alignment and durable performance are priorities for DT-03 1/10 on-road setups; always confirm fitment prior to installation.

How should I set up the arm for repeatable geometry?

Install using the same reference points every time and torque fasteners consistently; the machined face helps reduce variation between runs when you keep hardware and ball-joint positions identical.

Is this more durable than stock plastic arms?

Aluminium offers greater wear resistance for mounting faces, but overall durability depends on impacts and how the car is driven; metal arms resist deformation better under normal on-road use.

Will I need to change other suspension parts?

You may wish to review bushings, ball-studs and shock settings after fitting metal arms, since increased stiffness can shift load distribution and require small tuning tweaks.

Can I see exactly what is included?

Check the product listing images and notes for an itemised contents list; some sellers ship only the arm while others include additional fasteners or spacers.
