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

Aluminium front lower mount for BB-01 chassis

This anodized blue aluminum front lower suspension arm mount is a scale replacement intended for the TAMIYA BB-01 (BBX) chassis, offered as JR-TBB03-LB by Jazrider. It replaces the front lower arm mounting point with a metal alternative while keeping stock geometry and mounting locations for straightforward fitment on BB-01 style setups.

As a direct-fit component, the part uses the existing attachment points on the BB-01 (BBX) chassis. Installation requires transferring the original hardware and linkages to the new mount; verify fastener condition and alignment before final tightening. The anodized aluminum body is designed to resist wear at the suspension pivot and maintain a stable interface between the lower arm and chassis during normal RC use.

Replacing the plastic mount with an aluminium unit provides a firmer pivot location that can reduce unwanted flex at the lower arm connection, helping to preserve predictable steering and suspension response during tuning. This hop-up supports repeatable geometry adjustments and can improve handling consistency for track or casual driving.
