This set of aluminium front knuckle arms is intended for the TAMIYA XV-01 chassis and is supplied under the JR-XV100-BK part code. The metal replacements are specified to reduce wear points compared with stock plastic knuckles during regular hobby use.
The black anodized surface provides corrosion resistance and a harder contact surface to extend service life. These parts are produced to fit the standard XV-01 steering assembly and suspension pick-up points; installation normally requires moving bearings and fasteners from the original components to the alloy pieces.
Using aluminium components can change strain distribution through the front end, reducing flex around the hub and helping the steering hold a consistent feel over repeated runs. After installation, periodically check fasteners and bearing seats to catch early wear before it affects performance.
