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

Blue anodized aluminum knuckle arm for BB-01 (BBX)

This aluminum front knuckle arm is produced by JAZRIDER for use on Tamiya BB-01 (BBX) scale on-road models. It replaces the stock plastic knuckle arm to provide a firmer steering linkage and improved resistance to wear during regular driving or track sessions.

Installation uses the vehicle's original mounting points and the existing hardware and bearings from the stock assembly. When fitting, confirm there is no binding in the steering travel, ensure ball stud seating is correct, and check for any interference with suspension components or steering links.

As a direct replacement, this aluminum knuckle arm sharpens steering feedback and reduces deformation under load, making it suitable for hobbyists seeking a durable upgrade while preserving BB-01 (BBX) chassis geometry.
