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

Aluminum front knuckle for BB-01 (BBX)

This JAZRIDER JR-TBB01-GU aluminum front knuckle arm is made for the Tamiya BB-01 (BBX) chassis as an RC-scale replacement and tuning part in gun metal finish. It serves as a direct steering and suspension interface, intended to replace stock plastic knuckles to improve durability and reduce flex under load.

Installation notes: the knuckle mounts to existing steering knuckle pivots and linkage points on the BB-01 (BBX) chassis. Retain original hardware where possible and check steering geometry after fitting. Inspect wheel hub alignment and ball bearings when reinstalling wheels to ensure free movement and consistent steering response.

Tuning role: this aluminum knuckle provides a stiffer steering pivot that helps maintain toe settings and reduces unpredictable deflection during hard cornering or uneven surfaces. Use it alongside matched uprights and linkages when adjusting steering throw and suspension behaviour to achieve a more repeatable handling balance.
