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

Aluminium Front Knuckle Arm for TB04

This aftermarket front knuckle arm is a drop-in aluminium option for the TAMIYA TB04 platform, supplied as 1 pr for RC-scale use. It is intended as a durable steering component to serve the steering linkage and wheel spindle area on the TB04 chassis.

In RC setups the front knuckle arm locates the steering pivot and influences steering geometry and wheel alignment during suspension travel. Replacing or switching to an aluminium knuckle provides a different part stiffness and interface compared with the original component, which can be used when evaluating handling and setup changes.

Installation is straightforward for TB04 assemblies that accept the same mounting points and hardware, test-fit before final assembly to confirm free movement, and ensure clearance around the steering linkage and wheel hub. Sold as 1 pr (pcs).
