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

Upgraded rear arms for BBX BB-01

This 7075 aluminium rear suspension arm set is a direct replacement for the TAMIYA BBX BB-01 chassis and is supplied under GPM part number BBX022. The alloy arms retain the original mounting geometry while offering greater stiffness compared with the stock plastic components.

Fit these arms when you want a firmer rear end and more consistent suspension response. The parts are specified as 7075 aluminium and note accommodation for larger inner bearings, so check bearing bore and hub clearances on your BBX BB-01 before installation. These arms alter lateral stiffness and feedback at the rear mounting points as part of a tuning approach.

As a 7075 aluminium replacement, these rear arms suit hobbyists aiming to reduce rear flex and improve repeatability on the BBX BB-01; confirm fitment and bearing sizes before fitting to ensure correct assembly and clearance.
