The JAZRIDER blue aluminium front knuckle arm is a practical upgrade aimed at Tamiya BB-01 (BBX) hobbyists who want a longer lasting steering part. It reduces flex under load and helps keep steering inputs predictable during club runs or weekend practice.
Install the arm using the original mounting points and check screw torque after the first few runs. Keep an eye on pivot points and replace any worn pins for consistent steering performance.
