Plastic semi-axles

Plastic axle shafts to keep your slot car transmission in order

Axle shafts are one of the components that accumulate the most wear in a frequently used slot car. The reference AV20406 from Avant Slot offers a direct solution: to replace or substitute the original axle shafts with a part specifically manufactured for their models, ensuring the correct fit and expected performance on track.

Function and performance

Axle shafts connect the differential or central axle to the wheels, transmitting the motor's movement to the ground. When an axle shaft is worn, bent, or broken, the car loses traction unevenly, vibrates, or simply stops moving smoothly. Replacing them in time is one of the most basic —and rewarding— maintenance tasks for any slot car.

Being made of plastic, these axle shafts offer a combination of lightness and absorption of small irregularities, common characteristics in the transmission assemblies of cars from these brands.

Compatibility

Manufactured by Avant Slot, these axle shafts are compatible with their own models and also with cars from Fly, which share transmission geometry in many of their versions. If you have doubts about whether they fit your specific model, please consult us before placing your order.

Assembly and preparation

Changing axle shafts does not require special tools in most cases. It is enough to remove the wheels, extract the damaged axle shaft, and place the new one, ensuring it is well seated in its housing. It is advisable to take advantage of the disassembly to check the condition of the bearings or bushings, the wheels, and the crown gear, thus completing a comprehensive maintenance of the transmission.

Common mistakes

• Installing the axle shaft without first checking the condition of the bushing or bearing: if these are damaged, the new axle shaft will suffer again prematurely.
• Forcing the fit of the axle shaft if it does not enter smoothly: this may indicate that it is not the correct reference for that model.
• Ignoring a slight vibration on track attributing it to the tyre, when in reality the source may be a bent axle shaft.

Frequently asked questions

Which Fly cars are these axle shafts compatible with?

They are compatible with Fly models that share transmission geometry with Avant Slot cars. If you have the specific model, consult us and we will confirm compatibility before you order.

How many units are included in the pack?

The original description does not specify the exact number of units. We recommend checking the product in-store or contacting us to confirm.

Is it necessary to change both axle shafts at the same time?

It is not mandatory, but if one is very worn, it is likely that the other is in a similar condition. Changing them at the same time ensures an even distribution of the transmission and avoids having to disassemble the car again in a short time.

Can they be used with sidewinder or inline motors?

The axle shafts act on the drive axle regardless of the motor configuration, so they are compatible with both arrangements as long as the axle and housing are correct for the model.
