Neodymium magnet for magnetic suspension 4x1.5mm (8x)

The magnet that keeps your Slot.it magnetic suspension alive

The magnetic suspension systems from Slot.it are one of the most refined solutions offered by the brand to improve track contact and corner stability. Their proper functioning largely depends on the magnets acting on the suspension being in perfect condition. The SICN09 is precisely the official replacement that meets this need: a set of eight neodymium magnets measuring 4x1.5 mm, with the power and dimensional tolerances required by the system.

Features of the SICN09

• Material: neodymium (NdFeB), high-density rare-earth magnet with a strong magnetic flux.
• Dimensions: 4 mm diameter × 1.5 mm thickness.
• Quantity: 8 units per pack.
• Official Slot.it reference: SICN09.

Function and performance

In Slot.it's magnetic suspension, these magnets work by exerting a retaining force or preload on the moving elements of the assembly. Maintaining the correct geometry of the system requires that the magnets have not lost power or show dimensional irregularities. Neodymium is the ideal material for this application: it offers a very high force-to-size ratio in an extremely compact format, allowing for integration without altering the weight or mass distribution of the chassis.

Over time and with the impacts inherent in competition, the magnets can fracture — they are inherently fragile pieces — or lose some of their magnetism. Having a replacement pack like the SICN09 allows for immediate action without waiting for a faulty magnet to compromise the car's performance on track.

Compatibility and installation

This replacement is designed for Slot.it chassis and suspension kits that specify 4×1.5 mm magnets in their magnetic system. Before installation, it is advisable to check in the manual or the corresponding chassis specification that the dimensions match exactly, as Slot.it uses different magnet references depending on the suspension model.

During installation, pay attention to polarity: neodymium magnets attract with considerable force for their size and can chip if brought together abruptly. Handle them with plastic or wooden tweezers and work on a clean surface, free of metal shavings that may adhere to the magnet before placing it in its housing.

Common mistakes

• Confusing polarity: if the magnet does not seat correctly or the suspension does not respond as it should, it is likely inverted. Carefully remove it and check the orientation.
• Forcing the fit: the housing in the chassis usually has tight tolerances. If the magnet does not enter smoothly, check that the diameter is correct (4 mm) before applying pressure.
• Not verifying the size: Slot.it has several magnet references for different applications. Always confirm that the chassis requires the 4×1.5 mm format.

Ideal for…

Preparers and club racers using Slot.it chassis with magnetic suspension who want to always have the appropriate replacement on hand. Also for those building Slot.it chassis kits from scratch and needing to complete the suspension system with original specification magnets.

Frequently asked questions

How many magnets does the SICN09 pack include?

The pack includes 8 neodymium magnets measuring 4×1.5 mm.

Are they standard neodymium magnets or do they have any specific Slot.it specifications?

They are neodymium magnets with the dimensions and tolerances specified by Slot.it for their magnetic suspension system. Although the measurements are standard (4×1.5 mm), we recommend always using the official replacement to ensure the correct fit in the chassis housings.

Can I use these magnets in chassis from other brands?

If another chassis requires magnets measuring exactly 4×1.5 mm, the dimensions are compatible. However, Slot.it designs and certifies them for their own systems; for other brands, consult the original manufacturer's specifications.

Why do neodymium magnets break?

Neodymium is a very hard but brittle material. Side impacts or collisions — common in track accidents — can chip or fracture them. Therefore, it is advisable to always have a replacement pack on hand.

Do I need any special tools to install them?

It is not essential, but it is recommended to use plastic or wooden tweezers to avoid the magnets attracting each other suddenly and chipping. Work in a clean environment, away from metal shavings or dust.

The Slot.it SICN09 is an official replacement pack of 8 neodymium magnets (4×1.5 mm) for Slot.it magnetic suspension systems. These high-strength rare-earth magnets are essential to keep the suspension geometry and performance intact on your Slot.it chassis. A must-have spare part for slot car club racers and builders working with Slot.it suspension kits. Available at Ministry of Hobby with fast international shipping.
