TAMIYA BB-01 (BBX) Aluminum Front Knuckle Arm by JAZRIDER JR-TBB01-BK  [JR-TBB01-BK]

Aluminum front knuckle arm for BB-01 (BBX)

This JR-TBB01-BK is an RC-scale aluminum front knuckle arm produced by JAZRIDER for the TAMIYA BB-01 (BBX) chassis. It is intended as a metal alternative to the stock plastic knuckle arm, providing a more rigid steering pivot point suited to hobby-grade model cars.

Material and role: the part uses aluminum for improved wear resistance compared with typical plastic parts, and it serves as the front wheel steering knuckle that links the suspension and steering linkages on the BB-01 (BBX) layout. As an accessory it supports tuning efforts that prioritize steering precision and repeatable geometry under load.

Installation and fit: this knuckle arm is designed for the BB-01 (BBX) chassis mounting pattern and replaces the original front knuckle arm without requiring chassis modification. Use the existing mounting hardware and verify alignment and steering range after installation to avoid binding.

Maintenance and tuning tips: check for proper bearing fit and keep pivot points free of grit, inspect fasteners regularly, and consider balancing upgraded knuckles with matched hardware to maintain predictable steering feel during setup changes.
