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

7075 aluminum front knuckle upgrade for BB-01

This aftermarket front knuckle arm set is made for 1/10 scale TAMIYA BBX BB-01 applications and uses part number BBX021. The components are precision machined from 7075 aluminum to offer a firmer alternative to stock plastic arms, intended for hobby use on RC model cars only.

In service the parts locate on the front knuckle assembly and help refine steering response and alignment once fitted. Their main role is to increase front-end rigidity and to provide a long-lasting mounting point for the hub, bearings and steering linkages used on the BB-01 chassis.

Fitting is straightforward as a direct replacement for the original knuckle arms. Follow standard BB-01 front knuckle procedures: remove the wheel hub and bearings, transfer any required bearings or spacers, fit the new knuckle arm to the uprights using the original or supplied fasteners, then reassemble and check steering geometry and free play before running.

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 appropriate tools and torque practice for small fasteners and re-check after the first run.

These knuckle arms act as a durable aluminum replacement to support steering stability and tuning on TAMIYA BB-01 models; always confirm fitment and transfer bearings where required before use.
