TAMIYA TB04 Front Steering Knuckle Arm TB4021 by GPM  [TB4021]

Front Knuckle Arm Details

This aluminium front knuckle arm is an aftermarket, drop-in option for the TAMIYA TB04 chassis and is supplied as 1 pr for scale on-road cars. It is intended to act as a durable steering component serving the steering linkage and wheel spindle locations on the TB04.

The knuckle locates the steering pivot and influences how toe and camber react through suspension movement. Using an aluminium knuckle changes stiffness and the mechanical interface compared with the original part, and can be part of handling tests or setup revisions.

Installation is straightforward on TB04 assemblies with the same mounting geometry; test-fit before final assembly to confirm free rotation and adequate clearance around the steering linkage and hub. Sold as 1 pr (pcs).
