Slot.it Spring Washer

A small spare part that makes a difference in your Slot.it setups

The CRT-225 Spring Washer from Cumbre Racing Technologies is one of those components that go unnoticed until you need them. Designed for use in Slot.it assemblies, this washer serves an essential function in the suspension or spring mounting: maintaining the correct pressure, preventing unwanted movement, and ensuring that every adjustment you make to your car translates into predictable and consistent behaviour on the track.

Function and performance

Spring washers act as a retaining and load distribution element at the mounting points where suspension or guide springs are involved. Their correct presence in the assembly prevents the progressive loosening of screws and components subjected to continuous vibration, which is especially relevant in cars that accumulate long running sessions or compete in endurance formats.

In competition setups, a misplaced component can alter the geometry of the chassis, modify the ride height, or unbalance the load on the tyres. Having washers in good condition and of the correct size is part of the methodical work that separates a well-prepared car from one that simply runs.

Compatibility

This reference is aimed at Slot.it assemblies. If you have doubts about whether it fits exactly in your chassis configuration or the spring you are using, we recommend checking the technical documentation of your kit or consulting us directly.

Assembly and preparation

As it is a small component, its correct placement requires attention and the right tools. We recommend working on a clean and well-lit surface, and replacing washers whenever they show deformation, crushing, or signs of material fatigue. Do not reuse damaged washers: the cost of this component is minimal compared to the effect its poor condition can have on the assembly.

Presentation

The CRT-225 reference is supplied in a pack of over 30 units, making it a very practical option for preparation workshops, club teams, or enthusiasts who prefer to have stock available and not rely on frequent restocking.

Frequently asked questions

What exactly is a spring washer used for in a slot car?

The spring washer acts as a retaining element between the spring and the support surface, preventing lateral movement and distributing the load evenly. Its presence is key for the spring to work correctly and to avoid unwanted play during operation.

Which Slot.it chassis is this washer compatible with?

The CRT-225 reference is aimed at Slot.it assemblies in general. To confirm the exact compatibility with your specific chassis or kit, we recommend consulting us or reviewing the technical documentation of your model.

How many units are included in the pack?

The pack includes over 30 units, sufficient to cover several setups or to have a spare stock on hand for an entire season.

How often should I check or replace spring washers?

We recommend inspecting them at each disassembly of the suspension or mounting assembly. If they show deformation, crushing, or any signs of fatigue, replace them immediately. As a low-cost component with a high impact on performance, it is not worth the risk of reusing a washer in poor condition.

Is this type of spare part suitable for competition?
