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

Rear lower link for Tamiya DT-03

This precision aluminium rear lower suspension arm is made for the Tamiya DT-03 chassis and is model JR-DT301-LB. It serves as a replacement-style upgrade to increase dimensional stability in the rear suspension without changing the chassis geometry.

Engineering notes highlight the use of aluminium to resist working and deformation compared with original plastic arms, while maintaining the DT-03 mounting interfaces. The arm is suitable for model owners prioritising reliable handling and reduced wear across repeated running sessions.

To install: remove the stock lower arm, inspect and reuse compatible pins and retainers if serviceable, then fit the JR-DT301-LB. Check pivot clearance, tighten to the chassis manufacturer's torque recommendations, and re-check alignment and suspension travel post-install.

Ideal when you need a reliable, dimensionally stable rear lower arm for DT-03 upkeep or staged performance improvements; always inspect alignment after fitting.
