Tamiya TB-04 Rear Aluminium Knuckle Arm TB4022 by GPM  [TB4022]

Replacement aluminium knuckle for TB-04 rear end

This aluminium rear knuckle arm is supplied as 1 pr and is intended as a direct replacement for the plastic rear knuckle used on Tamiya TB04 touring car chassis where compatible.

Construction and effect: aluminium increases part rigidity and wear resistance versus standard plastic, aiding alignment retention during repeated cornering and helping to stabilise rear behaviour during tuning sessions.

Installation notes: designed for TB-04 series fitment; confirm compatibility with your chassis variant. Installation normally requires hub removal, possible bearing transfer, and reassembly with the original screws. After fitting, verify wheel bearing preload and correct thread engagement.

Tuning considerations: expect a modest change in steering feedback and rear traction when switching to aluminium; alter toe or camber in single increments and check screw torques to avoid bearing binding.
