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

Durable front knuckle arm for BB-01 (BBX)

This aluminum front knuckle arm is produced by JAZRIDER for Tamiya BB-01 (BBX) on-road kits. The component replaces the original plastic knuckle arm to provide improved steering stiffness and greater resistance to wear during regular running or competitive use.

The part installs using the stock mounting points and existing hardware and bearings. During fitting, make sure steering movement is free from binding, check ball stud engagement, and ensure there is no interference with steering linkages or suspension pivots.

In tuning terms, the alloy knuckle arm reduces flex and sharpens steering feedback, making it a practical upgrade for enthusiasts who want durability and consistent handling while keeping the BB-01 (BBX) geometry unchanged.
