TAMIYA XV-01 Aluminum Front Knuckle Arms by JAZRIDER JR-XV100-BK  [JR-XV100-BK]

Aluminum front knuckle arms for XV-01

This is an RC-scale aluminum front knuckle arm set intended for the TAMIYA XV-01 chassis, supplied under the JAZRIDER JR-XV100-BK part code. The components replace typical plastic knuckles to provide a firmer steering mounting point on scale competition and club-run models.

The parts are finished in black anodized aluminum to resist wear from normal hobby use, and they are intended to integrate with the existing XV-01 steering assembly and suspension pick-up points. Installation usually involves removing the stock knuckles and transferring any bearings and fasteners from the original parts before fitting the aluminum pieces, then checking steering throw and alignment after installation.

From a tuning perspective, aluminum knuckles change how loads are transferred through the steering and front suspension, which can reduce flex at the hub and make steering response feel firmer. When fitting metal hop-ups, confirm wheel camber and toe settings, and inspect for binding at full steering lock to avoid accelerated wear on steering linkages or the servo.
