TAMIYA TT02 Alloy Front Knuckle Arm with Bearing by GPM TT2021B  [TT2021B]

Alloy front knuckle for TT02

This GPM TT2021B alloy front knuckle arm is an aftermarket steering hub designed for TAMIYA TT02 chassis use. It replaces the standard plastic/nylon front knuckle to provide a metal alternative that integrates a ball bearing for the steering pivot. The part is supplied as a 1pr set and is intended for hobby-grade RC tuning and maintenance only.

Installation requires retaining or reusing the original nylon components where indicated, the kit note specifies it must be used with the original nylon piece. When fitting, check alignment with existing steering linkage and confirm bearing orientation so the steering pivot moves freely without binding. Use the existing hardware and torque settings recommended for your TT02 assembly.

Functionally this alloy knuckle serves a tuning role: it increases assembly stiffness compared with a stock nylon item and places the bearing at the pivot to reduce friction and wear. Expect a measurable change in steering feel and component longevity when used with a correctly maintained steering system, but plan your setup changes incrementally when tuning handling.

Use this alloy knuckle when seeking a firmer steering assembly and reduced pivot friction, and ensure compatibility with your TT02 steering hardware by reusing the specified original nylon components during installation.
