SC-3DP Racing Guide with Screw. Dimensions: 24.3x7mm

The Scaleauto SC-3DP Racing Guide: Geometry Designed for Competition

The SC-3DP Racing Guide with Screw from Scaleauto (SC-1654A) is a preparation piece designed for those who leave nothing to chance in their assembly. With dimensions of 24.3 x 7 mm and a pin of 3.5 mm, it offers precise geometry that promotes firm contact with the track and a clean response in braking and acceleration transitions.

Main Features

• Dimensions: 24.3 x 7 mm
• Pin: 3.5 mm
• Fixing: includes screw
• Manufacturing Technology: 3DP (precision 3D printing)
• Brand: Scaleauto
• Reference: SC-1654A

Function and Performance

The guide is one of the most critical elements of any competitive slot car. Its geometry directly determines how the vehicle follows the track, especially in fast corners where lateral inertia places greater demands on the piece. Scaleauto's 3DP technology allows for very tight tolerances, resulting in smoother and more predictable movement.

The included fixing screw facilitates assembly and ensures that the guide is well anchored to the chassis, preventing play that could affect track performance.

Compatibility

This guide is designed to work with Sport rail (compatible with Scaleauto and Slot.it tracks, among other systems with this slot geometry). Before installation, it is advisable to check that the chassis housing accommodates a 3.5 mm pin and that the dimensions of the blade (24.3 x 7 mm) fit correctly with your track's rail.

Assembly and Preparation

Assembly is straightforward thanks to the included screw. However, it is important to ensure that the guide's rotation in its housing is free but without excessive lateral play: too much play penalises steering, and too much rigidity can cause derailments on elevation changes. A moderate tightening torque on the screw is sufficient to secure the position without blocking the necessary pivoting movement.

To get the most out of it, combine it with good, well-tensioned braids and check the condition of the rail before each session.

Ideal for…

Club racers competing on Sport rail tracks who need a reliable guide, with well-defined standard measurements and easy to replace between heats. It is also a good option for builders looking to standardise the guide set across multiple cars in the same category.

Frequently Asked Questions

What type of track is this guide compatible with?

It is designed for Sport rail, used in Scaleauto and Slot.it track systems, among others. It is not directly compatible with Universal rail (Scalextric, Ninco), which has a different geometry.

Is the screw included in the pack?

Yes, according to the product information, the guide is supplied with the fixing screw included.

What diameter is the pin?

The pin measures 3.5 mm. Check that your chassis housing accepts that diameter before placing the order.

What advantage does 3DP manufacturing offer over a standard guide?

The precision 3D printing technology allows for very exact and repeatable geometries, with tolerances that are difficult to achieve with conventional moulding in small series. The result is a piece that is more consistent in its final measurements.

Do I need special tools to assemble it?

No. A suitable screwdriver for the included screw is sufficient. It is advisable to use some form of play gauge to check lateral play once installed.

The Scaleauto SC-1654A SC-3DP Racing guide with screw is a precision slot car component measuring 24.3x7mm with a 3.5mm pin, engineered for Sport rail systems. Ideal for club racers and builders looking for consistent performance and easy fitting on Scaleauto and Slot.it compatible tracks. A reliable upgrade for competitive slot car preparation.
