TAMIYA TT01/TT01E Aluminum Rear Upper Arms Upgrade JR-TT105-BK by Jazrider  [JR-TT105-BK]

Rear Upper Arm Upgrade for TT01 Series

The JR-TT105-BK kit contains aluminum rear upper suspension arms made for the TAMIYA TT01 and TT01E range. These are designed to replace the original plastic arms while matching the factory mounting points so they fit standard hinge pin positions and rear suspension layouts.

In tuning practice the stiffer aluminum arms act as a firmer anchor for rear geometry, aiding consistency when making incremental setup changes. They suit hobbyists who run repeated alignment checks and want stable handling behavior without swapping other chassis parts.

Fitment advice: the parts target the TT01 family and use the same chassis attachment locations; check compatibility with your specific TT01 or TT01E variant and keep or source the small fasteners required for final assembly.
