Slot.it Spring Hook

The spare part that keeps your RT4 cradle and Slot.it spring perfectly anchored

The Slot.it Spring Hook CRT-221 from Cumbre Racing Technologies is a replacement part specifically designed to work with the RT4 cradle in combination with the Slot.it spring. With this pack of 16 units, you will have plenty to keep several chassis ready or to replace worn hooks without having to stop your preparation sessions.

Function and performance

The spring hook is one of those elements that goes unnoticed until it fails. Its function is to properly retain the spring on the cradle, ensuring that the guide responds with the correct pressure and that the chassis behaviour is consistent and predictable. A damaged hook can cause variations in guide height or loss of contact in corners, directly affecting lap times.

Compatibility

• Compatible with the RT4 cradle from Cumbre Racing Technologies.
• Designed for use with Slot.it springs.

Assembly and preparation

Assembly is straightforward and does not require special tools. Simply place the hook in its position on the RT4 cradle to secure the spring. We recommend periodically checking the condition of these hooks, especially during competition sessions where chassis experience greater mechanical stress. Having 16 units in the pack ensures you always have a spare on hand without waiting for a new order.

Common mistakes

The most common mistake is ignoring the wear of the hooks until the problem affects track performance. A quick visual check before each session is enough to detect any cracked or deformed hook in time. Replacing them preventively is the smartest practice in competition.
