This set of 7075 aluminium rear suspension arms is supplied for the TAMIYA BBX BB-01 under GPM part number BBX022 and is offered as a stiffer replacement for stock plastic arms. The components keep the original mounting geometry for straightforward installation on the BBX BB-01 chassis.
Install these arms to tighten rear-end behaviour and make suspension response more predictable. The arms are specified as 7075 aluminium and accommodate larger inner bearings according to the listing, so verify bearing bore and hub clearances before fitting. As an upgrade, they influence lateral stiffness and rear feedback during use on rough surfaces.
These alloy rear arms suit hobbyists focused on off-road tuning and a firmer rear end on the BBX BB-01; always confirm fitment and bearing sizes ahead of final assembly.
