This machined aluminum front knuckle arm fits directly on the TAMIYA BB-01 (BBX) chassis and comes in a durable red anodized finish. It is intended to substitute the stock plastic knuckles, giving a more rigid pivot for the steering linkage and improved abrasion resistance where the suspension and steering interface.
Fitment is straightforward using the BB-01 (BBX) stock mounting arrangement and existing steering hardware and bearings. When installing, confirm clearance between the knuckle and tie rods and torque fasteners to eliminate slop while preserving free steering motion.
Tuning advice: an aluminum knuckle lowers component flex at the front, which can tighten steering feel and influence body roll. Ideal for drivers seeking crisper steering or a longer-lasting part for heavy use; monitor nearby linkages and bearings for altered wear patterns.
