This RC-grade aluminum rear knuckle arm is made as a direct replacement for the TAMIYA TA01, TA02, DF01 and FF01 family. It replaces the stock plastic item with a metal unit that helps preserve suspension geometry and provides a solid mounting surface for hubs and axle hardware.
The gun metal finish is cosmetic and protective, and the component is machined to match the factory mounting points so it installs without chassis modification. Under load the metal knuckle helps keep toe and camber more consistent, improving handling predictability during extended sessions.
Fitting is straightforward for those familiar with model assembly: remove the OEM knuckle, move over bearings or locating pins, and fasten the replacement with the original hardware. After installation verify bearing alignment and that the driveshafts and carriers move freely through the suspension travel.
