3Racing Shock Tower Reinforcement TT01

Greater rigidity in the TT01 suspension with the 3Racing shock tower brace

The Tamiya TT01 chassis is one of the most popular in the world of competitive and recreational RC modelling due to its versatility and accessibility. However, its original shock towers can suffer from flex or wear under high demands, compromising the suspension geometry and the car's behaviour. The 3Racing shock tower brace (ref. 3RTT01-E32) is specifically designed to address this weak point.

Function and performance

This component acts as an additional structural element over the TT01 shock towers, reducing deflection under load and maintaining the correct alignment of the dampers throughout the session. The result is a more consistent suspension response, especially on tracks with irregularities or during prolonged runs where the fatigue of the original plastics becomes noticeable.

Compatibility

Designed exclusively for the Tamiya TT01 chassis and its derived variants that share the same shock tower layout. Before installation, verify that your version of the TT01 maintains Tamiya's standard suspension architecture, as some third-party conversions may modify this anchor point.

Assembly and preparation

The installation process follows the usual logic of 3Racing reinforcement components: it integrates over the existing structure without the need to modify the chassis. We recommend taking the opportunity during assembly to check the condition of the dampers and ball joints, as once the rigidity of the towers is improved, any play in those components will be more noticeable on track.

Common mistakes

• Not verifying the chassis version: although the TT01 has several iterations, most share the same shock tower geometry; confirm before installation.
• Excessive tightening: too high a torque on the screws can introduce unwanted stresses in the surrounding plastic. Adjust judiciously.
• Omitting suspension adjustment after installation: with the stiffer towers, it is worth reviewing and readjusting the spring preload to make the most of the improvement.

Frequently asked questions

Is it compatible with the TT01E (E version of the TT01)?

The reference 3RTT01-E32 is aimed at the TT01 family, usually including the E variant. Still, we recommend checking against the breakdown of your specific chassis before placing an order.

Do I need special tools to install it?

No. The assembly is done with the usual screws and tools used in RC work (hex or star screwdrivers depending on the included screws), without the need for milling or structural modifications.

Does it significantly improve on-track behaviour?

On chassis with some use, where the original plastic already shows some fatigue, the difference is noticeable: the suspension works more uniformly and the car responds with greater predictability in corners.

Can it be combined with other 3Racing chassis reinforcements for the TT01?

Yes. 3Racing offers a range of preparation components for the TT01 designed to work together. Check the rest of the catalogue to build a coherent set of upgrades.

The 3Racing TT01-E32 suspension tower brace is a precision upgrade part for the Tamiya TT01 chassis, reinforcing the shock tower structure to reduce flex and maintain consistent suspension geometry. Ideal for RC car enthusiasts looking to improve handling, durability and on-track performance of their TT01 build. Available at Ministry of Hobby with fast shipping across Europe.
