BBX BB-01 Aluminium Rear Arms Upgrade BBX022 by GPM  [BBX022]

Rear arm replacement for BBX BB-01 chassis

This 7075 aluminium rear suspension arm set is an RC-scale replacement specified for the TAMIYA BBX BB-01, listed as GPM part BBX022. The design preserves the original mounting points while offering an alloy alternative to the factory plastic arms.

Use these arms to reduce rear flex and achieve more repeatable suspension travel. The arms are made from 7075 aluminium and are shown to accommodate larger inner bearings, so double-check bearing bores and hub clearance on your BBX BB-01 before fitting. As an upgrade, they change lateral stiffness and the rear's feedback characteristics.

These aluminium rear arms are aimed at hobbyists who want a stiffer rear end and consistent behaviour from the BBX BB-01; always confirm fitment and bearing dimensions prior to assembly.
