TAMIYA TT01/TT01E Rear Upper Arm Upgrade (Aluminum, Light Blue) JR-TT105-LB by Jazrider  [JR-TT105-LB]

Rear upper arm upgrade for TT01/TT01E

This aluminum rear upper suspension arm is made for TAMIYA TT01 and TT01E chassis and arrives in a light blue anodized finish. It replaces the original plastic upper arm to provide a more rigid mounting point and a repeatable fit for setup work.

To fit the arm remove the rear wheel hub and take off the factory upper arm, then install the aluminum piece using the vehicle's original mounting hardware. After fitting, check that the ball stud is aligned and that the suspension moves freely to prevent binding.

For chassis tuning the rear upper arm influences rear geometry and driver feedback. A stiffer aluminum component helps cut flex under cornering loads and gives a steadier platform when adjusting rear toe and camber.
