TAMIYA TT01/TT01E Aluminum Rear Upper Suspension Arms by JAZRIDER JR-TT105-RD  [JR-TT105-RD]

Rear upper suspension arm overview

This JAZRIDER JR-TT105-RD rear upper suspension arm is an RC-scale replacement part designed for the TAMIYA TT01 and TT01E chassis. Manufactured from aluminum, the red anodized arms provide a stiffer mounting point compared with standard plastic arms, helping to stabilise camber and roll characteristics during cornering.

The component is intended as a direct-fit upgrade for hobby use, supporting setup changes and incremental tuning of suspension geometry. Fitment focuses on the upper rear suspension link area and affects how load transfers through the rear suspension during acceleration, braking, and turns, allowing model builders to fine-tune handling balance without modifying major chassis components.

Installation notes: install using the stock hinge pins and hardware from your TT01/TT01E, check clearances with the body and shock towers after fitting, and verify wheel alignment before running. Routine inspection is recommended to ensure fasteners remain secure after initial test runs.
