This aluminum front upright knuckle arm set is intended for TAMIYA TA-series RC models and is supplied as JR-TA101-DB in dark blue. The components are designed to replace the factory plastic uprights, lowering steering pivot flex and stiffening the connection between the wheel hub and steering linkage while keeping the stock mounting points intact.
Installation notes: uprights accept the vehicle's original kingpin and ball-stud placements and use the existing hub carrier hardware. During trial fitting, confirm ball-stud engagement and wheel hex alignment; small removal of paint or thread-lock on mating surfaces may be required to permit smooth movement. These parts are for scale RC chassis applications only.
Performance notes: aluminum uprights change load transfer through the front suspension, reducing compliance and improving steering consistency under load. After fitting, re-check toe, camber, and steering geometry to re-establish the handling balance you prefer.
