Control spring

The spring that provides the exact response to your controller

When the trigger of your controller loses tension or fails to return accurately, the problem usually lies here: a worn, fatigued, or simply broken spring. The SP138905 from Sloting Plus is the original replacement that resolves this issue in just a few minutes, restoring the feel and response you expect in every corner.

Function and performance

The spring is the component that determines the return tension of the trigger. A spring in good condition ensures that power modulation is linear and predictable, which is critical during long club sessions or competitions. Sloting Plus manufactures it from steel to ensure constant elasticity and fatigue resistance, preventing it from losing properties with continued use.

Compatibility and installation

This spring is designed for controllers in the Sloting Plus range. Before placing your order, we recommend checking that your controller model is compatible by consulting the reference in the official catalogue or contacting us. Installation is straightforward and does not require special tools: simply open the controller casing, remove the damaged spring, and insert the new one into its housing.

Installation and preparation

Having 2 units in the bag has a clear advantage: you have a spare for the workshop or to carry in your track bag. A practical tip is to check the condition of the spring periodically, especially if you notice that the trigger does not return smoothly or has lateral play. Replacing it preventively avoids surprises in the middle of a session.

Frequently asked questions

Which Sloting Plus controllers is this spring suitable for?

It is specifically manufactured for the Sloting Plus controller range. If you have doubts about compatibility with your specific model, please consult us before placing your order.

Why does a controller spring fatigue or break?

Continuous use, impacts, or a sudden opening of the controller can cause deformation or breakage of the spring. It is a normal wear part in any frequently used controller.

Do I need special tools to change it?

No. Generally, a suitable screwdriver is enough to open the controller casing. The housing itself guides the placement of the spring.

Does the bag include 2 identical springs?

Yes, the 2 units included are identical. You can use one for immediate repair and keep the other as a spare.

Does the spring affect power modulation?

Directly. The tension of the spring determines how much force you need to move the trigger. A worn spring can lead to imprecise feel or inconsistent return, affecting control on the track.
