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

Precision front knuckle arms for BB-01 applications

This aftermarket front knuckle arm set is designed for 1/10 scale TAMIYA BBX BB-01 chassis and is supplied as part number BBX021. The components are precision machined from 7075 aluminum to deliver improved stiffness compared with standard plastic knuckles, intended for hobbyist RC vehicle use.

Functionally the parts mount to the front knuckle uprights and enhance steering response and alignment under load. They provide a rigid mounting surface for the hub, bearings and steering linkages used on the BB-01 platform, helping to reduce flex and maintain consistent geometry during operation.

Installation is a direct swap for the original knuckle arms: remove the hub and bearings, transfer required bearings or spacers as needed, fit the knuckle arm to the uprights with original or supplied fasteners, then reassemble and verify steering geometry and free play prior to running the model. Observe correct torque for small fasteners and re-check after initial testing.

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. Ensure proper tool selection and torque control when fitting hardware.

These precision-machined alloy knuckle arms are an engineered upgrade to support steering stability and component longevity on BB-01 cars; verify fitment and bearing placement prior to use.
