This JAZRIDER replacement is an RC-scale front upright knuckle arm set designed for TAMIYA TA01, TA02W, DF01 and Hotshot chassis. The parts are intended to be used as direct replacements for plastic uprights to provide a consistent aluminium mounting point for steering components and suspension links. The light blue finish identifies the alloy pieces and helps visual orientation during setup.
Fitment is intended for the listed Tamiya chassis and assumes reuse of the original fasteners and bearings. Installation typically requires removal of the front hubs, transfer of existing bearings and steering links, and secure mounting using the stock hex screws; users should verify fit and alignment before final tightening. These arms act as a tuning item to stabilise steering geometry and to reduce flex at the upright under load.
The description focuses on compatibility, installation context, and the tuning role of aluminium uprights on RC touring and vintage Tamiya models, and does not imply use beyond RC-scale vehicles.
