SC Spring Hook

The SC Spring Hook CRT-213: small part, great importance in your chassis setup

In the world of competitive slot racing, details make the difference. The SC Spring Hook from Cumbre Racing Technologies (reference CRT-213) is one of those components that go unnoticed until they fail. Its function is to properly retain and anchor the spring in the chassis, ensuring that the response of the suspension or the pressure system on the guide is constant and predictable.

Function and performance

The spring hook is the element responsible for holding the spring in its working position within the chassis. When this part is worn, deformed, or broken, the spring loses correct tension, resulting in erratic behaviour of the car on track: loss of contact with the braids, unstable guide, or unpredictable chassis response in corners.

Having this spare part on hand is essential for any tuner or club driver who wants to resolve the issue in the pit without losing race time.

Compatibility and installation

This hook is designed for SC series chassis from Cumbre Racing Technologies. Before purchasing, we recommend confirming that your chassis corresponds to this product family. Installation is straightforward and does not require special tools: simply remove the spring, place the new hook in its housing, and reinstall the spring ensuring the correct tension for your setup configuration.

Common mistakes

• Reusing a bent hook or one with a worn housing: although it may seem functional, it can come loose during the race.
• Installing the spring with excessive tension to compensate for a deteriorated hook: this unnecessarily stresses other parts of the chassis.
• Ignoring the periodic wear of this part in the routine maintenance of the car.

Ideal for…

Club drivers and tuners competing with Cumbre Racing Technologies SC series chassis who need to maintain a minimum stock of critical spare parts to avoid relying on urgent shipments during the championship season.
