Tamiya TT-02 Rear Lower Suspension Arm Aluminum Upgrade - TT02-13107-RD by Jazrider  [TT02-13107-RD]

Aluminum rear lower arm — installation focus

This aluminum rear lower suspension arm is an RC-scale replacement designed specifically for the Tamiya TT-02 chassis. Machined aluminum increases stiffness at the mounting point compared with stock plastic arms and is intended for chassis tuning and repair.

Fitment is limited to the TT-02 family; the part mounts at the rear lower suspension position to retain the chassis geometry. The red finish makes it simple to identify during setup checks and routine maintenance.

Installation notes: the arm mounts to the existing TT-02 suspension points using the original interfaces. When replacing this arm, confirm alignment of suspension links and ball studs and tighten fasteners to recommended kit torque values to prevent binding.

Tuning role: using an aluminum rear lower arm reduces flex at the lower pivot, helping alignment remain consistent under load and delivering a predictable response when adjusting ride height and dampers. This is an RC component only and not for real vehicle use.
