This aftermarket aluminium front knuckle arm is a direct replacement compatible with the TAMIYA TB04 platform and is supplied as 1 pr for on-road RC models. It is intended as a tougher steering component for the linkage and wheel spindle area on the TB04 chassis.
The front knuckle sets the steering pivot and has a clear effect on wheel alignment during suspension travel. Replacing the original with an aluminium unit changes stiffness and the contact interface with the hub, which is useful when testing handling or setup modifications.
Fitting should be simple on TB04 layouts that use the same mounting points; always test-fit to confirm steering freedom and linkage clearance before completing the install. Sold as 1 pr (pcs).
