TAMIYA BB-01 (BBX) Precision Front Lower Arm Mount (Aluminum) - JR-TBB03-LB by Jazrider  [JR-TBB03-LB]

Replacement aluminum lower mount for BB-01

This anodized blue aluminum front lower suspension arm mount is an RC-scale replacement produced for the TAMIYA BB-01 (BBX) chassis and marketed as JR-TBB03-LB by Jazrider. It offers a metal alternative to the original plastic lower-arm mount while preserving the factory geometry and mounting points for straightforward fitment on BB-01 type layouts.

Manufactured as a direct-fit component, the mount uses the BB-01 (BBX) existing attachment points. Installation involves transferring the original hardware and checking alignment and fastener condition before final torque. The anodized finish helps limit wear at the suspension pivot and maintains a steady interface between the lower arm and chassis under typical RC operating conditions.

From a setup standpoint, replacing a plastic mount with an aluminium unit provides a firmer pivot that reduces unwanted flex at the lower-arm connection, aiding predictable steering and suspension behaviour while tuning. The part is useful for achieving repeatable geometry and dependable handling during both practice and event running.
