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

Precision aluminum knuckle for BB-01 (BBX)

The JR-TBB01-GU aluminum front knuckle arm is manufactured for the Tamiya BB-01 (BBX) chassis as an RC-scale replacement and tuning part in a gun metal finish. It replaces the stock plastic knuckles to increase durability and cut down flex under load while acting as the steering and suspension interface.

Installation notes: the knuckle fits onto the factory steering pivots and linkage mounting points used on the BB-01 (BBX) chassis. Reuse original hardware where appropriate and recheck steering geometry after installation. Verify wheel hub alignment and bearing seating when refitting wheels to preserve free rotation and consistent steering response.

Tuning role: this aluminum knuckle stiffens the steering pivot to help hold toe settings and reduce unpredictable deflection during hard cornering or rough terrain. Pair it with matched uprights and links when refining steering throw and suspension balance for more repeatable handling.
