Tamiya GF01/TL01 Rear Knuckle Arm - Aluminium GF022 by GPM  [GF022]

GF01/TL01 rear knuckle overview

The GF022 is an aluminium rear knuckle arm intended for use on Tamiya GF01 and TL01 chassis, supplied as a 1pr set. It serves as the rear suspension pivot and the mounting point for rear steering linkages on the compatible chassis.

Replacing the original plastic knuckle arms, this machined aluminium component provides a firmer mounting face and helps keep geometry consistent through setup changes. Fitment follows the original GF01/TL01 rear hub layout and uses the same attachment points, so steering and drivetrain geometry remain limited to chassis adjustment options.

Installation notes: confirm wheel hub alignment and suspension clearance, tighten fasteners to the chassis maker torque recommendations, and ensure bearings and pins are correctly positioned before operating. Recheck for loosening after initial runs.

Tuning role: designed as a replacement and setup component for drivers refining rear toe and steering behaviour on GF01/TL01 cars, offering a stable aluminium pivot where repeatability is required.

Ideal when you want a simple aluminium upgrade for GF01/TL01 rear pivots during setup or testing. Always confirm fitment prior to competitive use.
