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

Aluminum rear upper arms for TT01/TT01E

This is an RC-scale aluminum rear upper suspension arm designed for TAMIYA TT01 and TT01E chassis. Finished in light blue anodized coating, the part replaces the stock plastic upper arm to offer a firmer mounting point for the rear suspension and a consistent fit for tuning tasks.

Installation requires removal of the rear wheel hub and detaching the factory upper arm, then fitting the aluminum arm using the vehicle's existing mounting hardware. After installation confirm ball stud alignment and free movement of the suspension to avoid binding.

In practical tuning the rear upper arm affects rear suspension geometry and feedback to the chassis. Using a stiffer aluminum arm can reduce flex under load and provide a more consistent response during cornering, making it useful for drivers adjusting toe and camber at the rear.
