3RACING Front Hub M05

3RACING Aluminium Front Knuckle for Tamiya M05 and M06 PRO

When looking to improve steering response in Tamiya's M series chassis, replacing the original plastic front knuckles with machined aluminium parts is one of the most common steps among club racing RC enthusiasts. The reference 3RM05-05/LB from 3RACING is designed specifically for this purpose.

Function and Performance

The front knuckle is the connection point between the steering spindle and the wheel. Being made of aluminium, it gains stiffness and reduces flex under lateral load, resulting in more precise and predictable steering. Additionally, aluminium dissipates heat generated by friction during long sessions better than the original plastic.

Compatibility

• Tamiya M05
• Tamiya M06 PRO

Always check the specific version of your chassis before placing an order to ensure that the mounting geometry is correct.

Installation and Preparation

The replacement process follows the same procedure as with the original part. It is recommended to check the fit of the bearings and steering pins during installation, and to apply a minimal amount of light grease at the pivot points to ensure smooth and lasting movement. If you are preparing the car for competition, it is a good time to also check the steering geometry (toe-in and camber angle) once the new knuckle is installed.

Considerations

• The colour may vary depending on the batch finish (light blue according to the suffix /LB of the reference).
• Sold as a spare part; verify if you need one unit or a pair depending on the part of your chassis you will be working on.
• As a machined aluminium part, any strong impact may bend it; however, its replacement is much simpler and more immediate than with broken plastic parts.

Frequently Asked Questions

Is it a significant improvement over the original plastic knuckle?

Yes. Aluminium offers greater structural rigidity, which reduces lateral deflection during turns and improves steering consistency, especially on technical circuits with many tight corners.

Is it compatible with the standard Tamiya M06 in addition to the M06 PRO?

According to the manufacturer's information, the indicated compatibility is for the M06 PRO. If you have the standard version of the M06, check the technical data sheet from 3RACING or contact us before placing your order.

Do I need special tools for installation?

No. The installation uses the same screws and standard tools from the Tamiya M05/M06 PRO chassis. A hex screwdriver of the appropriate size and a wrench for the steering pins are sufficient.

What does the suffix /LB in the reference mean?

The suffix /LB refers to the finish colour: Light Blue. 3RACING typically offers its anodised aluminium parts in various colours; this finish corresponds to light blue.

Can it be used in official Tamiya club competitions?

It depends on the regulations of the specific category or club. In classes that allow the replacement of suspension and steering parts with aluminium equivalents, this knuckle is a perfectly valid option. Check your club's regulations before installing it on a regulated competition car.

The 3RACING front knuckle arm for Tamiya M05 and M06 PRO (ref. 3RM05-05/LB) is a precision-machined aluminium upgrade part designed to replace the stock plastic steering knuckle. It delivers improved steering rigidity and more consistent handling, making it a popular choice among RC touring car enthusiasts and club racers running Tamiya M-chassis vehicles.
