The JR-TA201-DB kit contains dark blue anodized aluminum front knuckle uprights sized for 1/10-scale Tamiya TA02, TA03, FF01 and CC01 chassis. These uprights replace standard plastic units to give improved stiffness and more consistent setup results over repeated runs.
Since uprights form the connection between steering linkages and the front suspension, they influence steering precision, caster and scrub radius when used alongside other geometry adjustments. The following notes cover fitment and practical setup tips without assuming additional hardware is included.
