TAMIYA BB-01 (BBX) Aluminum Servo Stay Mount JR-TBB04-BK by Jazrider  [JR-TBB04-BK]

Rigid servo stay for BB-01 (BBX)

This JR-TBB04-BK aluminum servo stay mount is an RC-scale replacement designed for TAMIYA BB-01 (BBX) chassis builders seeking a firmer, more consistent servo mounting point. It installs into the chassis' original servo location and creates a rigid interface between the servo and front end to help preserve steering geometry under load.

Fitment uses the BB-01 (BBX) stock mounting points and hardware. During installation, align the servo spline before the final torque and avoid overtightening to protect plastic threads. The alloy construction cuts local flex versus the stock plastic stay, but always confirm clearance with your servo case and horn before final assembly.

On the setup bench, a stiffer stay improves repeatability by keeping control link geometry stable, which is helpful when dialing toe or ackermann. Treat this as a tuning accessory for scale chassis refinement rather than a primary steering control device.
