TAMIYA BBX BB-01 Front Knuckle Arms 7075 Aluminum BBX021 by GPM  [BBX021]

Aluminum front knuckle set for BB-01 chassis

This knuckle arm set fits 1/10 scale TAMIYA BBX BB-01 applications and carries part number BBX021. The pieces are machined from 7075 aluminum to provide a more rigid option than the factory plastic arms, intended for hobby RC use only.

The knuckle arms mount on the front uprights and help improve steering precision and alignment stability when installed. They are intended to add front-end rigidity and deliver a robust mounting point for hubs, bearings and the steering linkages used on the BB-01 platform.

Installation mirrors the original knuckle replacement routine: remove the hub and bearings, move any necessary bearings or spacers across, attach the replacement knuckle arm to the uprights with the original or supplied fasteners, then rebuild and confirm steering geometry and free play before driving.

Packing details and supplied hardware are listed below in-line for clarity so you can confirm the contents before installation: knuckle arm - 2pcs, grade 12.9 black round head screws 3x10 - 4pcs, bearing 5x13x4 - 4pcs. Use correct tools and re-check fasteners after the first run.

These aluminum knuckle arms are a straightforward upgrade to support steering stability on BB-01 cars; always verify part compatibility and bearing fit before fitting.
