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

Aluminum front lower suspension mount for BB-01 chassis

This anodized blue aluminum front lower suspension arm mount is an RC-scale replacement part developed for the TAMIYA BB-01 (BBX) chassis and listed as JR-TBB03-LB by Jazrider. It replaces the stock front lower arm mounting point with a metal component while retaining the original geometry and attachment locations for straightforward fitment on BB-01 style setups.

Designed as a direct-fit mounting component, the part uses the existing attachment points on the BB-01 (BBX) chassis. Installation involves transferring the original hardware and linkages to the new mount; confirm fastener condition and alignment before final tightening. The anodized blue aluminum body resists wear at the suspension pivot and maintains a stable interface between the lower arm and chassis under typical RC driving loads.

As a tuning upgrade, swapping the plastic mount for an aluminum unit delivers a firmer pivot location that can reduce unwanted flex at the lower arm connection, helping to keep steering and suspension behaviour predictable during setup changes. This hop-up supports repeatable geometry adjustments for more consistent handling at the track or during routine maintenance.
