TAMIYA TT01 Precision Alloy Front Knuckle Arm TT021 by GPM  [TT021]

Precision alloy knuckle for TT01 setups

This alloy front knuckle arm is an aftermarket replacement tailored for the TAMIYA TT01 platform. The alloy construction, supplied with collars and screws, replaces the standard plastic knuckle to give a firmer steering pivot and enhanced resistance to repeated loading during tuning and track sessions.

From a setup perspective, the component reduces flex where the steering linkage meets the upright, improving steering repeatability and consistency lap after lap. It interfaces cleanly with stock TT01 steering hubs and tie-rods and secures using the supplied collars and screws without requiring modifications to the base chassis.

Installation follows a straightforward replacement routine: remove the stock knuckle arms, position the alloy arm into the upright, and secure with the supplied collars and screws. After installation, confirm steering travel and wheel alignment and make precise tie-rod adjustments as part of normal setup work.
