Tamiya DT-03 Compatible Rear Lower Suspension Arm JR-DT301-LB by Jazrider  [JR-DT301-LB]

DT-03 rear lower suspension arm

This aluminium rear lower suspension arm fits the Tamiya DT-03 chassis and is identified as model JR-DT301-LB. It is an upgrade-style replacement intended to provide improved stiffness and reliable pivot behavior without altering factory suspension geometry.

The arm's aluminium construction is chosen to limit deformation under load versus standard plastic arms, and it interfaces with the DT-03 mounting layout and hardware. The part benefits drivers who want repeatable camber response and extended component life.

Fitting is generally straightforward: remove the original rear lower arm, reuse compatible pins and retainers where suitable, and install the JR-DT301-LB. Confirm pivot free play, torque to manufacturer specs, and recheck suspension travel and wheel alignment after installation.

Select this arm for a more dimensionally stable rear lower link on DT-03 cars, and always verify alignment following installation.
