The JR-TBB04-RD aluminum servo stay is produced for compatibility with the TAMIYA BB-01 (BBX) chassis and replaces the original plastic stay with a machined alloy part. The item is described strictly as an RC model accessory.
Installation aligns with the chassis' existing servo mounting holes and the red anodized finish serves as a clear visual marker during setup and maintenance.
As an upgrade, the aluminum stay increases stiffness at the servo mount to help hold servo position under load, supporting steering consistency and repeatable tuning adjustments.
