TA01 Front Knuckle Arm Set Precision Aluminium TA1021 by GPM  [TA1021]

Precision alloy knuckles for TA01 applications

This aftermarket front knuckle arm set is supplied as a direct-replacement accessory for the TAMIYA TA01 chassis. The alloy arms are engineered to align with the TA01 steering and suspension geometry, offering a metal alternative to the stock plastic items suitable for hobbyists focused on reliable setup and repeatable handling.

Operational role: the knuckle arm secures the wheel hub and interfaces with suspension and steering linkages, so correct seating on the TA01 knuckles and link points is essential. The component is designed to work with the chassis mounting points and standard fasteners; confirm side-specific orientation during installation.

Assembly guidance: remove the original front knuckle arms and transfer any required bushings or spacers, inspect bearings and hinge pins, then install the alloy arms ensuring smooth steering movement through full suspension travel. After fitting, perform a toe and play inspection and adjust as necessary for your setup.

Performance notes: swapping plastic arms for aluminium alters stiffness at the wheel pivot which can stabilise geometry under load and affect steering feedback. Use these alloy arms to reduce flex at mounting points, then recalibrate alignment and damping to achieve the intended handling characteristics.

Offered as a practical upgrade for TA01 setups, this aluminium front knuckle arm set supports more stable suspension geometry for tuning and track consistency. Ensure original inserts are reused and confirm alignment after installation.
