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

TT01 front knuckle alloy replacement

This alloy front knuckle arm is an aftermarket replacement designed for the TAMIYA TT01 chassis. The alloy body, supplied with collars and screws, replaces the stock plastic knuckle to provide a stiffer mounting point for steering and front suspension parts.

For tuners and racers focusing on consistent handling, the piece reduces flex at the knuckle to improve steering precision and survive repeated loads typical in touring car use. It interfaces with the standard TT01 steering hubs and tie-rods and secures with the included collars and screws without the need for chassis modification.

Installation is a direct swap: remove the factory knuckle arms, fit the alloy arm into the upright, and fasten with the supplied collars and screws. After fitting, recheck steering throw and wheel alignment and fine-tune tie-rods or ackerman as needed for optimal track performance.
