TAMIYA BBX BB-01 Aluminium 7075 Rear Suspension Arms by GPM BBX022  [BBX022]

Rear suspension arm upgrade for BBX BB-01

This aluminium rear suspension arm set is an RC-scale replacement part produced for use on the TAMIYA BBX BB-01 platform, supplied under GPM part number BBX022. The design intent is to provide a rigid alloy option where the stock components are typically plastic, maintaining the original mounting geometry and fit for the BBX BB-01 chassis.

Use this part when you want consistent suspension geometry and reduced flex at the rear mounting points. The arms are specified as 7075 aluminium and the listing indicates accommodation for larger inner bearings, so verify bearing bore and hub clearances on your BBX BB-01 before installation. This component plays a tuning role by altering lateral stiffness and feedback through the rear suspension assembly.

As an aluminium replacement part, these rear arms are intended for hobbyists seeking a stiffer rear end and repeatable suspension behavior on the BBX BB-01 chassis; check fitment and bearing sizes before fitting to ensure proper assembly and clearance.
