TT02 rear hubs

Adjust the rear geometry of your TT02 with Yeah Racing aluminium knuckles

The Yeah Racing TT02 rear knuckles (ref. YE-TT02-007-3) are a performance part aimed at those who want to go a step beyond the stock plastic on their Tamiya TT02 chassis. Made from aluminium and featuring a 3° inclination, they allow for more precise adjustment of the rear geometry, which is particularly relevant in club racing environments or in setups aimed at improving the model's dynamic behaviour.

Function and performance

The rear knuckles are one of the components that most influence the stability and response of the rear end. Replacing the original plastic parts with machined aluminium versions offers several direct advantages:

• Increased structural rigidity: aluminium does not deform under load, resulting in more predictable and repeatable behaviour.
• Controlled geometry: the 3° inclination is factory specified, eliminating variability that may arise with worn plastic parts or those with wide tolerances.
• Superior durability: a part that withstands the usual impacts on track or in intensive use better.

Compatibility

These knuckles are specifically designed for the Tamiya TT02 chassis, one of the most widely used radio control platforms in 1/10 scale modelling and club racing. Before installing them, it is advisable to check that the specific version of the TT02 you are working with supports this 3° geometry, as different tuning configurations may require different angles.

Installation and preparation

The replacement is direct: these knuckles occupy the same position as the original stock ones. It is recommended to check the tightness of all screws related to the rear end after installation and to verify the alignment of the axle before heading to the track. A small adjustment in the setup can make a noticeable difference in the car's behaviour.

Common mistakes

• Mixing knuckles of different angles between the left and right sides without being aware of it: always mount the same angle on both sides unless the setup explicitly requires otherwise.
• Not checking the wheel hub bearing when making the change: it is a good opportunity to replace it if it has play.
• Over-tightening the aluminium fixing screws: use the appropriate torque to avoid damaging the threading.

Ideal for…

TT02 drivers competing in club categories or simply enjoying tuning and refining their car. Also for those who have noticed wear or deformation in the original knuckles and are looking for a higher quality and more durable replacement.

Frequently asked questions

What is the purpose of the 3° angle in the rear knuckles?

The camber angle influences how the tyre contacts the ground during corners. A value of 3° is a common setup in preparations aimed at improving rear traction and corner stability.

Are they compatible with all variants of the Tamiya TT02?

They are designed for the TT02 chassis in general, but it is always advisable to check compatibility with the exact variant of your model before installation, as Tamiya has released various versions of this platform over time.

Are they sold in pairs or individually?

Check the packaging contents at the time of purchase. The reference YE-TT02-007-3 corresponds to the units as distributed by Yeah Racing; we indicate this in the product sheet.

Do I need special tools to install them?

No. The installation is straightforward and does not require special tools beyond the usual ones for maintaining a TT02: Allen keys of the appropriate size for the rear end screws.

What advantage does aluminium have over the original plastic?

Aluminium offers greater rigidity, better dimensional tolerance, and more durability against impacts. In intensive use or competition, this is particularly noticeable in the consistency of the car's behaviour throughout the session.
