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

Precision aluminum stay for BB-01 (BBX)

The JR-TBB04-BK aluminum servo stay is an aftermarket replacement tailored for TAMIYA BB-01 (BBX) chassis owners who want a less compliant servo mounting solution. It occupies the chassis' existing servo slot and gives a rigid contact between servo and front suspension to resist deformation during cornering.

Fitting is straightforward on BB-01 (BBX) frames using the original mounting points. Before tightening, verify servo spline alignment and avoid overtightening to protect thread inserts. The aluminum stay lowers flex compared to stock plastic parts, but check clearance with your specific servo and horn to avoid binding.

For setup work, a firmer stay can make steering trimming more consistent because link geometry remains stable under load. Consider this item a tuning upgrade for scale performance rather than a replacement for core steering components.
