Medium suspension springs

Tune the suspension of your Thunderslot with the medium springs TH-SSK006M

These medium hardness suspension springs are a specific spare part from Thunderslot for the motor mount. When you are looking for that middle ground between the lively response of a soft spring and the firmness of a hard one, medium springs are the natural starting point for any setup adjustment.

Function and performance

The suspension spring works directly on the motor mount, regulating how much freedom of movement the power unit has relative to the chassis. A medium hardness offers a balanced behaviour: it absorbs track irregularities without allowing the motor to oscillate excessively, resulting in more consistent traction and a predictable response when accelerating.

It is the usual starting point for tuning setups on mixed circuits, with varying radius corners or surfaces that combine fast sections and technical areas.

Compatibility and installation

These springs are designed for Thunderslot chassis that incorporate a motor mount with a suspension system. Check the manual of your specific model to confirm the correct reference before installing them.

Changing springs does not require special tools. With fine-tipped pliers and some practice, the replacement can be done on the workbench in a few minutes. It is advisable to work carefully to avoid losing small parts during disassembly.

Usage recommendations and common mistakes

• Do not mix springs of different hardness on the same mount: the response of the chassis will be asymmetric and difficult to interpret.
• If you notice a loss of traction in slow corners, try softer springs. If the car is unstable at high speed, harder springs may be the solution.
• Regularly check the condition of the springs: material fatigue can gradually alter the behaviour of the car, sometimes without being obvious at first glance.
• Always keep a spare set. They are small parts that can easily be lost during setup changes in competition.

Frequently asked questions

What is the difference between Thunderslot soft, medium, and hard springs?

The difference lies in the elastic constant of each spring, that is, the force required to compress it. Soft springs allow more movement for the motor mount and favour traction on tracks with many curves. Hard springs provide greater firmness and stability at high speeds. Medium springs are the balance between the two and the recommended starting point for any setup.

How many units are included in the TH-SSK006M pack?

The available information does not specify the exact number of units per pack. We recommend checking the product sheet or contacting us before placing your order.

Are they compatible with chassis from other brands?

They are designed for Thunderslot chassis. Compatibility with other brands will depend on whether the diameter and length of the spring match the motor mount's fittings in question. We cannot confirm compatibilities outside of Thunderslot models without prior verification.

How do I know if I need to change the springs on my car?

If the behaviour of the car has changed without apparent reason, if you notice it losing traction or if the response is inconsistent between sessions, it is worth checking the condition of the springs. Over time and use, they can lose part of their original tension.

Can I combine springs of different hardness to achieve an asymmetric setup?

Technically it is possible, but it is not a common or recommended practice as a starting point. Mixing hardness can introduce variables that are difficult to interpret during tuning. It is preferable to always work with springs of the same type and change only one variable at a time.
