This RC-scale aluminum front knuckle arm set is produced for compatibility with XV-01 chassis and is listed under the JR-XV100-GU model identifier. It is intended as an aftermarket replacement where users prefer alloy components to reduce steering deflection compared with the standard plastic knuckles.
The parts mount to the XV-01 steering assembly using the original bosses and hardware. Typical installation reuses pivot balls, spacers and bearings from the stock knuckles; check for any required spacer adjustments when combining with nonstandard hubs or drive shafts.
Aluminum knuckles influence steering feedback and can stabilise camber under load, which alters how the car reacts in high-speed transitions and cornering. After fitting, confirm toe and camber values and ensure the steering and suspension operate freely through their full range.
