This aftermarket set supplies machined aluminium front upper suspension arms compatible with the Tamiya TT01 and TT01E chassis, finished in light blue to combine visual appeal with greater rigidity than the original plastic parts.
Swapping to aluminium upper arms modifies the suspension's stiffness and transient response, which can affect understeer/oversteer balance and steering feedback. These arms are intended to be used alongside other setup adjustments such as shock tuning and alignment changes.
Installation uses the TT01-series' existing arm mounting locations and hardware, following the standard front upper arm replacement process. Confirm fit for your particular TT01 or TT01E variant and re-evaluate suspension geometry after fitting.
