The JAZRIDER JR-TFD01-RD front knuckle arm is a machined aluminium replacement designed to address the common failure points of the plastic knuckles on Thunder Shot, Thunder Dragon, Fire Dragon and Terra Scorcher models. It provides a stiffer mounting for the steering link and wheel hub, improving repeatable steering inputs.
Constructed from corrosion resistant aluminium with an anodised red finish, this knuckle arm reduces flex under load and resists deformation from impacts. The improved rigidity delivers more consistent toe control and reduces unplanned steering variance at corner exit.
Installation is intended as a bolt-in swap using existing fasteners on the compatible Tamiya platforms. When fitting, verify wheel pin and bearing condition and torque fasteners to recommended values. For tuners, small adjustments to steering linkage length may be used to fine tune Ackermann response.
