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

Durable 7075 knuckle arms for BB-01

This aftermarket knuckle arm set is produced for 1/10 scale TAMIYA BBX BB-01 use and is designated BBX021. Fabricated from 7075 aluminum, the parts present a stiffer replacement to stock plastic arms and are for hobby RC car applications only.

Mounted on the front knuckle assembly, these arms assist steering response and help maintain alignment under load. Their purpose is to strengthen the front end and to provide a reliable mounting point for hub assemblies, bearings and steering linkages on the BB-01 chassis.

Replacement follows the usual BB-01 knuckle routine: remove wheel hub and bearings, transfer any required bearings or spacers, fit the replacement knuckle arm to the uprights using original or supplied fasteners, then reassemble and verify steering geometry and free play before running the model.

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 suitable tools, observe correct torque, and re-check after initial use.

As an aluminum replacement these knuckle arms deliver increased steering stability and longevity for BB-01 models; always confirm fitment and bearing placement prior to operation.
