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

Rear upper arm summary

The Jazrider JR-TT105-RD rear upper suspension arm is a direct-fit replacement for the TAMIYA TT01 and TT01E chassis. Machined from anodized aluminum and finished in red, these arms provide a stiffer mounting point compared with the stock plastic pieces, helping stabilize camber and reduce unwanted roll during aggressive cornering.

Designed as an aftermarket upgrade for hobby use, the part supports incremental suspension tuning and setup changes. The upgrade concentrates on the upper rear link area and changes how load transfers across the rear suspension under acceleration, braking, and while turning, enabling drivers to refine balance without altering main chassis components.

Installation notes: fit using the factory hinge pins and original mounting hardware, check clearance with the body and shock towers after installation, and confirm wheel alignment before running. Inspect fasteners after initial test laps to ensure they remain secure.
