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

Front knuckle arm replacement for BB-01

This aftermarket knuckle arm set fits 1/10 scale TAMIYA BBX BB-01 cars and is identified as BBX021. Manufactured from 7075 aluminum, the parts are a more rigid substitute for the standard plastic knuckle arms, intended for hobby RC use only.

When fitted to the front uprights these arms assist steering precision and aid alignment retention. Their role is mainly to stiffen the front end and supply a robust mount for the hub, bearings and steering linkages on the BB-01 platform.

The set is supplied for direct replacement of the original knuckle arms. Install using standard BB-01 procedures: remove the hub and bearings, swap any necessary bearings or spacers, attach the new knuckle arm to the uprights with the original or supplied fasteners, then reassemble and check steering geometry and free play prior to 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 correct tools, observe recommended torque, and re-check after initial testing.

These aluminium knuckle arms serve as a strong replacement to improve steering stability and durability on BB-01 models; confirm compatibility and bearing placement before use.
