In-Line Offset Chassis 1.0mm

Precision to the millimetre: Slot.it In-Line Offset 1.0mm mount for long-can and flat motors

The reference SICH49B is the official Slot.it mount for inline setups with a 1.0 mm offset. An apparently small detail that, in the world of slot car racing preparation, makes a real difference in transmission, crown wear, and track behaviour.

Function and performance

The mount —also called motor support— is the part that secures the motor to the chassis and determines its relative position to the rear axle. In an inline configuration, the motor is oriented in line with the rear axle (longitudinally), which helps lower the car's centre of gravity and achieve a more balanced weight distribution.

The 1.0 mm offset allows lateral adjustment of the motor-pinion assembly to achieve optimal meshing between pinion and crown gear. This adjustment is particularly relevant when working with different combinations of pinions and crowns, or when aiming to minimise lateral play in the transmission for cleaner and more consistent traction.

Compatibility

• Designed for Slot.it chassis that support inline configuration.
• Compatible with long-can motors and flat / boxer type motors (among which Slot.it designates Boxer and Flat-6).
• Integrates into the Slot.it spare parts ecosystem, making it fully interchangeable with other mounts in the range according to the required offset.

Installation and preparation

The installation of this mount follows the standard process for Slot.it modular chassis: fitting into the designated anchors of the chassis and securing with the appropriate screws. Before finalising, it is advisable to check the pinion-crown meshing with the rear axle mounted, ensuring there is no excessive play or tightness that could cause friction. Correct meshing is perceived when manually rotating the axle: it should turn smoothly and without rattling.

If you are going to combine this mount with a new motor, remember to break it in with a few minutes of low-tension running before demanding full power. This protects both the motor and the mount itself.

Who is this mount for?

It is primarily aimed at club preparers and drivers who work with Slot.it chassis and want to fine-tune the drivetrain geometry to the maximum. It is also the direct replacement part if the original mount shows wear or breakage after intense competition sessions.

Frequently asked questions

What is the difference between a 1.0 mm offset and other offset values?

The offset indicates the lateral displacement of the motor relative to the central position. Each offset value is designed to achieve the correct meshing with a specific combination of pinion and crown gear, or to adjust the transmission in chassis with different manufacturing tolerances. Slot.it offers various offset values in its range of mounts so that the preparer can choose the most suitable for their setup.

Is it compatible with sidewinder or anglewinder motors?

No. This mount is specifically designed for inline configuration (longitudinal motor, in line with the rear axle). For sidewinder or anglewinder setups, Slot.it provides specific mounts for each geometry.

Which Slot.it chassis can I use it with?

The SICH49B mount is designed for Slot.it modular chassis that accommodate long-can and flat motors in inline position. Check the documentation of your specific chassis or the official Slot.it website to confirm exact compatibility with your model.

Do I need special tools for installation?

No special tooling is required. A screwdriver suitable for the chassis securing screw is sufficient. However, it is recommended to check the meshing before the first use on track.

Can I use it on Sport track?

The mount is an internal component of the chassis and does not depend on the type of track. Cars built with Slot.it chassis typically run on Sport track (Scaleauto, Slot.it), although the mount itself does not affect compatibility with the track.

The Slot.it SICH49B In-Line Offset 1.0mm motor mount is a precision replacement and tuning part for Slot.it chassis, compatible with long-can and flat/boxer motors in inline configuration. Designed for club racers and serious builders looking to fine-tune drivetrain geometry and achieve optimal pinion-to-crown mesh. A key component in any Slot.it inline setup.
