Hard Line F Stand

The inline mount that makes a difference in competition setup

The Inline Hard Block F from SRC (reference SRCRM1608) is a preparation piece specifically aimed at competition. Made from fibre-loaded plastic, it combines lightness and rigidity to provide a solid base for anchoring the motor in an inline position, meaning the motor shaft is perpendicular to the rear axle and longitudinally aligned with the chassis. This configuration lowers the centre of gravity of the assembly and promotes a more balanced weight distribution, which translates to greater stability and more consistent traction on the track.

Features and highlights

• Inline motor position: the motor is longitudinally aligned with the car, improving cornering behaviour and reducing gyroscopic effect.
• Fibre-loaded plastic: the material provides structural rigidity without adding unnecessary weight, which is crucial in competition where every tenth of a gram matters.
• Bending lock in the mount support: prevents unwanted movements of the motor-mount assembly during the race, ensuring that power transmission is constant and predictable.
• Pack contents:
  • 1 x LN-D Block F Mount
  • 4 x Screws 1.8 x 6ZN
  • 2 x Motor screw M2 x 4ZN

Function and performance

The mount is one of the most influential elements in the dynamic behaviour of a competition slot car. A rigid mount minimises energy loss due to deformation and ensures that the alignment between the pinion and crown gear remains constant, prolonging the lifespan of both parts and improving transmission efficiency. The Hard version from SRC is specifically designed for tracks and categories where rigidity prevails over flexibility, offering a more direct and predictable response.

Assembly and preparation

The pack includes all the necessary screws for assembly, making it easy to replace on the bench without the need to search for compatible metric sizes. The integrated bending lock in the support simplifies the setup process, as once correctly fixed, the assembly is immobilised without the need for additional parts. We recommend checking the alignment of the motor-rear axle assembly before finally tightening the screws, and verifying the clearance of the pinion with the crown gear to ensure optimal transmission.

Ideal for…

This mount is aimed at preparers and club drivers looking for rigidity and repeatability in their setups. It fits particularly well in competition categories where consistency in tuning is prioritised over adaptability to different types of track. If your driving style or the regulations of your championship require firm and uncompromising behaviour, the Block F Hard is your starting point.

Aspects to consider

As it is a hard version, this mount is not designed for very uneven tracks or with pronounced bumps where a mount with some flex might be advantageous. Check the regulations of your category before installing any preparation piece to ensure it meets the allowed specifications.

Frequently asked questions

What is the difference between a "hard" mount and a standard mount?

The hard version is made from a stiffer material, which reduces deformation under load and offers a more direct response. It is the usual choice in competition, while a mount with some flex may better absorb the irregularities of the track in recreational use.

What does it mean that the motor is in an inline position?

Inline indicates that the motor is oriented longitudinally, perpendicular to the rear axle. This lowers the centre of gravity of the assembly and improves stability, especially in fast corners.

Are the included screws sufficient for complete assembly?

Yes, the pack includes the 4 mount screws (1.8 x 6ZN) and the 2 motor fixing screws (M2 x 4ZN) necessary to complete the assembly.

Which chassis or models is this mount compatible with?

The available information does not specify the exact list of compatible chassis. We recommend consulting the official technical sheet from SRC or contacting our team to verify compatibility with your specific model.

Can I combine this mount with any inline motor on the market?

It is primarily designed for the range of inline motors compatible with SRC chassis, but specific compatibility depends on the dimensions of the motor. If in doubt, please consult before proceeding with the assembly.

The SRC SRCRM1608 Inline Hard Mounting Block F is a competition-grade slot car motor mount made from fibre-loaded plastic for maximum rigidity.
