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

Stiff servo mount option for BB-01 (BBX)

The JR-TBB04-BK aluminum servo stay is an RC accessory crafted for TAMIYA BB-01 (BBX) chassis users who prefer a firmer servo anchoring point. It installs into the stock servo location and forms a solid link between the servo and front end to reduce deformation under load.

Installation on BB-01 (BBX) frames uses the original mounting holes and standard hardware. Check servo spline alignment before final torque and avoid overtightening to protect plastic threads. The alloy reduces local compliance relative to the stock plastic stay, but ensure your servo case and horn clear the new bracket.

When tuning, a more rigid stay helps keep steering geometry consistent, which improves the repeatability of toe and ackermann adjustments. Use this as a handling upgrade for fine-tuning chassis behavior rather than as a substitute for core steering components.
