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

Front knuckle arm for TAMIYA TT01

This alloy front knuckle arm is an RC-scale replacement part produced by GPM for the TAMIYA TT01 platform. Designed to take the place of the standard plastic knuckle, the alloy body combined with the supplied collars and screws provides a stiffer mounting point for the steering linkage and front suspension components.

For hobbyists focused on handling and setup, this part serves a tuning role: increased steering precision through reduced flex at the knuckle, and improved durability under repetitive loads typical in touring car practice and club racing. The component interfaces with the stock steering hubs and tie-rods on TT01-style front assemblies and uses the included collars and screws to secure the fit without requiring alteration to the chassis.

Installation is a direct replacement procedure: remove the original knuckle arms, fit the alloy arm into the upright, and use the supplied collars and screws to fasten. After installation, check steering throw and wheel alignment before running; small geometry changes can be used to fine-tune handling when combined with other TT01 setup adjustments.
