Mitoos pivoting spring

Two steel springs to keep the Mitoos swinging arm in its exact position

When the suspension does not respond with the correct firmness, the car loses contact with the track during elevation changes and the guide stops working effectively. This pair of Mitoos CXM104 springs is the direct solution: original spare parts made of steel, specifically designed for the swinging arm of Mitoos chassis.

Technical specifications

• Contents: 2 swinging springs
• Material: steel
• Outer diameter: 4.7 mm
• Width: 4.5 mm
• Reference: CXM104
• Brand: Mitoos

Confirmed compatibilities

This reference is the original spring for the swinging arm for the following Mitoos chassis:

• Mitoos Panda RTR chassis (Ref. M905)
• Mitoos 75mm RTR chassis (Ref. M907)

If you have any of these chassis in intensive club use or have been using the same front end for a while, checking and replacing the swinging arm springs is one of the simplest maintenance tasks with the greatest impact on the car's behaviour.

Function and performance

The swinging arm allows the guide to follow the profile of the track independently of the chassis, absorbing track irregularities and maintaining electrical contact with the braids. The spring is the element that regulates the return tension: a fatigued or deformed one causes loose guide, loss of contact, and erratic driving, especially on tracks with raised joints or pronounced elevation changes.

Replacing with original Mitoos springs ensures that the suspension geometry returns to factory values without the need for additional adjustments.

Installation and preparation

The change is quick and does not require special tools. Simply disassemble the swinging arm, remove the worn spring, and install the new one while respecting the original orientation. As it is a standard replacement part, the fit is direct without modification.

Frequently asked questions

How many springs does this reference include?

The CXM104 pack includes 2 swinging springs.

Which Mitoos chassis are they compatible with?

They are confirmed for the Mitoos Panda RTR chassis (M905) and the Mitoos 75mm RTR chassis (M907). They are the original standard spring for both models.

When should the swinging arm springs be replaced?

When you notice that the guide has excessive play, the car loses electrical traction in fast sections, or the suspension does not return smoothly. In club use, periodic inspection of these small elements prevents larger driving issues.

Are they compatible with other Mitoos chassis?

Confirmed compatibility is with the M905 and M907 chassis. For other Mitoos models, we recommend checking the measurements (Ø 4.7 mm / 4.5 mm wide) against the specifications of the corresponding chassis before placing an order.

The Mitoos CXM104 is a pair of steel tipping springs designed as original spare parts for Mitoos slot car chassis. With an outer diameter of 4.7 mm and a width of 4.5 mm, they are the direct replacement for the swingarm suspension system on the Mitoos Panda chassis (M905) and Mitoos 75mm chassis (M907). Essential maintenance parts for slot car racing enthusiasts looking to keep their chassis geometry and guide performance at factory specification.
