This dark blue machined aluminum front upright knuckle arm set is compatible with TAMIYA TA-series cars and carries the part number JR-TA101-DB. The kit swaps in place of the stock plastic uprights to lower flex at the steering pivot and to provide a more solid junction between wheel hub and steering linkage while maintaining original mounting locations.
Fitment guidance: uprights are designed to use existing kingpin and ball-stud positions and accept the original hub carrier fasteners. During test fit check ball-stud seating and wheel hex alignment; minor removal of paint or excess thread-lock from contact surfaces may be needed to ensure unrestricted steering. For scale RC chassis use only.
Compatibility notes: switching to aluminum uprights shifts how the front suspension transmits forces, typically reducing compliance and improving steering repeatability. After installation, verify and adjust toe, camber, and steering geometry to recover your desired handling characteristics.
