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

Durable aluminum knuckle for BB-01 (BBX)

The JR-TBB01-GU aluminum front knuckle arm is intended for the Tamiya BB-01 (BBX) chassis as an aftermarket replacement and tuning component in a gun metal finish. It serves as the steering and suspension interface, replacing plastic parts to boost longevity and resist deformation under load.

Installation notes: mount the knuckle to the existing steering pivots and linkage points on the BB-01 (BBX). Retain original mounting hardware when suitable and re-evaluate steering geometry following fitment. Check bearing seating and hub alignment before final wheel installation to ensure smooth rotation.

Tuning role: by providing a stiffer steering pivot, the aluminium knuckle helps preserve toe settings and reduces unpredictable deflection on rough surfaces or during aggressive cornering. Use in concert with compatible uprights and linkages when tuning steering throw and spring balance for consistent handling.
