Tamiya BB-01 (BBX) Front Steering Knuckle — Aluminum JR-TBB01-GU Upgrade by Jazrider  [JR-TBB01-GU]

Performance-oriented front knuckle for BB-01 (BBX)

The JR-TBB01-GU aluminum front knuckle arm is built for the Tamiya BB-01 (BBX) chassis as a precision replacement and tuning part finished in gun metal. It acts as the direct steering and suspension interface and is intended to replace stock plastic knuckles to enhance stiffness and control.

Installation notes: the knuckle attaches to the BB-01 (BBX) steering pivots and existing linkage points. Keep original hardware where possible and re-calibrate steering geometry after installation. Verify bearing fit and wheel hub alignment during reassembly to maintain smooth operation.

Tuning role: this aluminium knuckle reduces steering pivot flex, helping to lock in toe settings and cut unpredictable changes during high-speed cornering. Combine it with matched uprights and links when adjusting steering throw and suspension behavior for improved repeatability.
