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

Front knuckle arms for BB-01

This aftermarket front knuckle arm set is made for 1/10 scale TAMIYA BBX BB-01 applications and is offered by GPM as part number BBX021. The components are machined from 7075 aluminum to provide a stiffer alternative to stock plastic pieces, intended for hobby use on RC model cars only.

Functionally the parts locate on the front knuckle assembly and assist steering response and alignment when installed. Their role is primarily to increase front-end rigidity and to provide a durable mounting point for the hub, bearings, and steering linkages used on the BB-01 chassis.

The set is supplied for straightforward replacement of the original knuckle arms. Installation follows standard BB-01 front knuckle procedures: remove the wheel hub and bearings, transfer any required bearings or spacers, fit the GPM knuckle arm to the uprights using the original or supplied fasteners, then reassemble and verify 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 practices for small fasteners and re-check after first run.

These knuckle arms serve as a durable, aluminum replacement to support steering stability and tuning on TAMIYA BB-01 scale models; confirm fitment and bearing transfer before use.
