Hard inline cradle

The inline cradle that makes a difference in your bench setup

The Avant Slot AV20560 hard inline cradle is a motor mount designed for inline configurations, meaning the motor is positioned longitudinally relative to the rear axle. This type of mounting lowers the car's centre of gravity, a highly valued advantage in club racing and any setup where cornering performance is a priority.

Main features

• Inline configuration: motor perpendicular to the rear axle, in line with the car, for a lower centre of gravity.
• Third adjustment pillar: incorporates a third support point that allows precise adjustment of the bench height, which is essential for optimising transmission and grip.
• Fibreglass-loaded material: the plastic used incorporates fibreglass, significantly increasing its density and resistance compared to conventional plastic cradles.
• Hard version: the rigidity of the assembly ensures a stable motor position, without flex that could affect transmission performance.

Function and performance

In an inline setup, the cradle is the element that anchors the motor to the chassis and transmits torque to the rear axle. A poorly adjusted cradle or one made from less rigid material can result in vibrations, loss of effective power, or premature wear of the crown gear and pinion. The hard version of this cradle from Avant Slot precisely avoids those problems: the fibreglass-loaded plastic maintains geometry under load, and the added third pillar allows fine height adjustment that typically requires filing or shimming in more basic cradles.

Compatibility and installation

This cradle is developed within the Avant Slot preparation parts ecosystem. To confirm the exact compatibility with your chassis or motor, we recommend consulting the official Avant Slot catalogue or contacting our technical team. We do not assign compatibilities that we have not been able to verify.

Ideal for…

• Preparers and club drivers working with inline setups who seek precise bench adjustment.
• Chassis builders needing a rigid and stable support for competition.
• Advanced enthusiasts wanting to explore the advantages of inline with a proven quality component.

Aspects to consider

As it is the hard version, the cradle does not absorb vibrations as a soft or flexible version would. This is an advantage in terms of precision and response, but it is worth considering depending on the type of track and motor you will be using. If you have doubts about which hardness best suits your setup, we are here to help.

Frequently asked questions

What is the difference between an inline cradle and a sidewinder?

In an inline configuration, the motor is placed perpendicular to the rear axle, in line with the car, which lowers the centre of gravity. In a sidewinder, the motor runs parallel to the rear axle, transversely. They are distinct geometries with specific behaviours and cradles for each.

What is the purpose of the third adjustment pillar?

The third pillar allows adjustment of the height of the motor relative to the chassis, which directly affects the engagement between pinion and crown gear. A good height adjustment reduces wear and improves transmission efficiency.

What advantage does fibreglass bring to the plastic?

The fibreglass loading increases the density and rigidity of the material, reducing flex under load and improving the durability of the part compared to unfilled plastic.

Is the hard version better than the soft version?

It is not a matter of better or worse, but of application. The hard version offers greater stability and precision in adjustment; the soft version may better absorb certain vibrations. The choice depends on the type of motor, track, and driving style.

Can I use this cradle on any inline chassis?

Compatibility depends on the chassis design. We recommend checking with the Avant Slot catalogue or consulting with our team before proceeding with the installation.

The Avant Slot AV20560 hard inline motor mount is a precision slot car component designed for inline motor configurations, where the motor sits longitudinally aligned with the car's axis. Built from fibreglass-loaded plastic for enhanced rigidity and density, it features a third adjustment pillar for fine-tuning motor height and drivetrain geometry. An essential upgrade for club racers and advanced builders seeking consistent performance and reliable inline setup on any compatible chassis.
