TAMIYA TA01 Alloy Front Knuckle Arm set by GPM TA1021  [TA1021]

Aluminum front knuckle arm for TA01

This aftermarket front knuckle arm set is a direct-replacement RC accessory produced by GPM for the TAMIYA TA01 chassis. The component is specified as an alloy front knuckle arm set intended to work with the TA01 steering and suspension layout, offering a metal alternative to the stock plastic parts for hobbyist tuning and durability objectives.

Functionally, the alloy knuckle arm locates the wheel hub and connects suspension and steering linkages, so fitment to the TA01 steering knuckles and steering linkage points is the primary compatibility consideration. Expect the part to use the chassis’ existing mounting points and fasteners; confirm orientation and left/right placement before final assembly.

Installation notes: remove the stock front knuckle arms and transfer any inserts or bushings that the chassis uses, inspect wheel bearings and pins for wear, then install the alloy arms aligning steering linkages and checking free movement through the suspension travel. After installation, verify toe and steering free play and make small adjustments as required by your setup.

Tuning role: replacing plastic arms with alloy parts changes stiffness and impact behavior at the wheel mounting points, which can affect steering feedback and suspension response. Use the alloy arms when you want consistent geometry under load, then reassess alignment and damping to retain predictable handling.

This GPM alloy front knuckle arm set is positioned as a drop-in upgrade option for TA01 owners who prefer metal suspension components for tuning consistency. Confirm parts transferred from the original assembly and recheck alignment after fitting.
