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

Alloy steering knuckle for TAMIYA TT01

This alloy front knuckle arm is an aftermarket replacement for the TAMIYA TT01 platform. Made from a durable alloy and supplied with collars and screws, it replaces the OEM plastic knuckle to give a firmer mount for the steering linkage and front suspension components.

Targeted at hobbyists who tune handling, this part helps tighten steering response by cutting flex at the knuckle and offering better resistance to repeated loads encountered in touring car runs and club racing. The arm interfaces with standard TT01 steering hubs and tie-rods and uses the included collars and screws to secure a correct fit without modifying the chassis.

Fitting is a direct swap: remove the original knuckle arms, install the alloy arm into the upright, and fasten with the supplied collars and screws. After fitting, verify steering travel and wheel alignment; small geometry tweaks combined with other TT01 setup changes can refine on-track behaviour.
