This 7075 aluminium rear suspension arm set is provided for the TAMIYA BBX BB-01 chassis and carries the GPM part number BBX022. The alloy arms maintain original mounting geometry while giving a stiffer option compared with standard plastic parts.
Choose these arms to reduce rear flex and improve suspension consistency. The components are specified as 7075 aluminium and are noted to accept larger inner bearings, so check bearing bore and hub clearance on your BBX BB-01 prior to fitting. The upgrade will alter lateral stiffness and rear handling characteristics as part of tuning adjustments.
As an aluminium replacement, these rear arms are aimed at modelers seeking reduced rear flex and more repeatable handling on the BBX BB-01; verify fitment and bearing dimensions before assembly.
