This RC-scale aluminum rear knuckle arm is a direct-replacement style component intended for hobby-grade TAMIYA TA01, TA02, DF01 and FF01 chassis. It serves as a durable alternative to standard plastic knuckles, providing consistent geometry for the rear suspension and a stable mounting point for hub assemblies and wheel axles.
The part is finished in gun metal and designed to fit the original mounting points on the listed chassis without requiring chassis modification. In typical use it helps maintain rear toe and camber under load, which supports predictable handling during tuning sessions and routine track practice.
Installation is straightforward for experienced modelers: remove the original knuckle, transfer any bearings or pins, and refit using the stock hardware. Check wheel bearing alignment and suspension pivot clearances after fitting, and confirm that drive shafts and hub carriers rotate freely through their range.
