Aluminum front upper suspension arm for TT01/TT01E

The JR-TT104-RD aluminum front upper suspension arm is an RC-scale replacement part engineered for TAMIYA TT01 and TT01E chassis. Machined from aluminum with a red anodized finish, it replaces the stock plastic arm to provide a firmer upper mounting point while keeping the original mounting geometry.

Installation uses the chassis' stock hinge pin and mount locations, so fitting typically only requires swapping the arms. During installation verify alignment and check for interference with steering links and shock towers; the increased stiffness can alter camber and overall suspension compliance, so re-check toe and camber after fitting.

For tuning, these aluminum arms reduce flex at the upper pivot and help stabilise roll behavior under load. They suit hobby-grade 1/10 touring setups for drivers who prefer metal components over stock plastic for more consistent handling and longer service life.
