Conical guide spring x2

The spring that keeps your guide where it should be

Within the spare parts for 1/32 scale slot cars, guide springs are one of those components that go unnoticed until they fail. The Avant Slot conical guide spring av20571 is responsible for applying the necessary pressure on the guide to ensure it remains well seated on the track at all times, especially during elevation changes, tight corners, and sudden braking.

Function and performance

The function of the conical spring is simple yet critical: it acts as an elastic retention element between the car body and the guide, absorbing track irregularities and ensuring that the braids maintain uninterrupted contact with the conductive rails. A damaged spring —deformed, fatigued, or with loss of tension— can cause electrical disconnections, loss of traction, or, directly, a guide that does not respond accurately.

The conical profile of this spring allows for a progressive distribution of force, preventing the guide from being too rigid (which would penalise cornering) or too loose (which would create instability).

Compatibility

This spring is designed for use in Avant Slot slot cars in 1/32 scale. To confirm the exact compatibility with your specific model, consult your car's manual or the official Avant Slot parts list, as the reference av20571 may vary in fit depending on the chassis used.

Installation and preparation

Changing guide springs is a quick operation that does not require special tools. Simply remove the guide from its housing, extract the worn spring, and install the new one, ensuring it is well centred before reassembling the unit. It is advisable to check the condition of the spring after a certain number of racing sessions, especially if the car shows signs of electrical contact loss or if the guide appears to move with too much play.

Common mistakes

• Continuing to run with a fatigued spring thinking it does not affect performance: even a minimal loss of tension can result in electrical cuts in corners.
• Forcing the spring when mounting the guide, which can deform it from the very first moment.
• Confusing the mounting direction of the conical spring: the end with the larger diameter must be oriented according to the design of the chassis housing.

Frequently asked questions

When should I change the guide spring?

When you notice that the guide has too much vertical play, that the car suffers frequent electrical cuts without an apparent cause in the braids, or if upon inspecting the spring you see that it is deformed or has lost its original conical shape.

Does this pack include 2 identical springs?

Yes, the reference av20571 includes 2 identical conical guide springs, sufficient to prepare two cars or have a spare on hand.

Is it compatible with other 1/32 slot brands?

It is specifically designed for Avant Slot cars in 1/32 scale. Compatibility with other brands depends on the diameter and depth of the guide housing of each chassis, so we recommend checking this before installing it in a car from another brand.

Does the spring affect cornering behaviour?

Yes, albeit subtly. A spring with the correct tension allows the guide to tilt slightly when taking corners without losing contact with the track, which improves the stability and electrical response of the car.
