Rally Guide Spring (x2)

The spring that keeps your guide in its exact position

The Rally Guide Spring (AV20556) is the official replacement part from Avant Slot to keep the guide properly tensioned on its rally chassis. It is supplied in a pack of 2 units, allowing you to always have a spare or replace both springs at once if wear suggests it.

Function and performance

The guide spring serves an apparently discreet but critical function: it exerts the necessary pressure to keep the guide seated on the rail at all times. Without the proper tension, the guide tends to float or fail to return correctly to its central position after a curve, resulting in loss of contact with the braids and an increased risk of derailment.

In rally chassis, where the body and suspension absorb irregularities in the terrain, a spring in good condition is even more important: it ensures that the guide maintains contact with the rail even when the entire car assembly is working under demanding conditions.

Compatibility

This spring is specifically designed for Avant Slot rally chassis. Before installing it, check that your chassis corresponds to this product family to ensure that the fit and tension are correct.

Installation and preparation

Replacing the guide spring is a straightforward operation that does not require special tools. Simply remove the guide, extract the worn or deformed spring, and place the new one, ensuring it is properly seated in its housing. A correctly installed spring should allow the guide to move freely vertically but without lateral play.

It is advisable to check the condition of the spring after a certain number of running sessions, especially if competing regularly, as material fatigue can reduce its recovery capacity without being visually evident.

Common mistakes

• Continuing to run with a deformed or insufficiently tensioned spring, causing intermittent loss of contact that is difficult to diagnose.
• Forcing the spring when mounting the guide, altering its original geometry.
• Replacing only the spring without checking the overall condition of the guide and braids, missing the opportunity for complete maintenance.

Frequently asked questions

Which Avant Slot chassis is this spring indicated for?

According to the information provided by Avant Slot, this spring is indicated for the brand's rally chassis. If you have doubts about whether your specific model is compatible, please consult us before placing your order.

Why are 2 springs sold instead of 1?

The pack of 2 units allows you to have an immediate spare or to renew both springs at once if wear is detected. In competition, having available spare parts prevents unexpected stops.

How do I know if my guide spring needs changing?

The most common symptoms are a guide that does not return well to the central position, frequent loss of contact without apparent cause, or a guide that feels loose when pressed with a finger. If you detect any of these symptoms, it is time to replace it.

Is it compatible with universal track or Sport track?

The spring acts on the car's guide, not on the track rail. Its function is independent of the track system you use, whether it is universal rail (Scalextric, Ninco) or Sport rail (Scaleauto, Slot.it).

The Avant Slot AV20556 Rally Guide Spring (pack of 2) is an original replacement part designed to keep the guide properly tensioned on Avant Slot rally chassis. Essential for maintaining consistent rail contact and reliable performance during club racing or casual slot car sessions. A small but decisive component for any Avant Slot rally car setup.
