The JR-TBB02-GU gun metal aluminium steering assembly is intended for the Tamiya BB-01 (BBX) chassis and serves as a direct-fit metal replacement for the stock plastic steering components to enhance rigidity.
Using an aluminium steering assembly reduces flex at the steering interface and gives more repeatable inputs during tuning and setup, which is useful when adjusting toe, caster or servo endpoints on BB-01 (BBX) cars.
Installation is usually a straightforward swap into the BB-01 (BBX) steering locations while keeping original mounting points and hardware where possible. Inspect fixings and linkage alignment, torque to your recommended spec, and check for any binding through full steering movement.
Routine checks of fasteners and mating surfaces between metal and plastic parts will keep steering feel consistent and help identify wear before it impacts handling.
