The Slot.it Inline Offset Crown: Precise Tooth Design for Those Who Leave Nothing to Chance

The reference SIGO26-AL is the 26-tooth crown from Slot.it designed exclusively for use in inline motor configurations (longitudinal motor, perpendicular to the rear axle) mounted on an Offset pod. The aluminium insert it incorporates provides rigidity and a much more solid grip on the axle than standard plastic versions, which is noticeable in torque transmission and consistency lap after lap.

Main Features

• Number of teeth: 26Z
• Insert: aluminium
• Compatible axle diameter: 2.38 mm
• Motor configuration: inline (motor in line with the car)
• Compatible pod: Offset only
• Brand: Slot.it

Function and Performance

With 26 teeth, this crown is positioned in a gear ratio range that favours progressive acceleration without sacrificing top speed on long straights, depending logically on the pinion it is combined with. The machined aluminium insert ensures that the crown is perfectly centred and fixed to the axle, eliminating play and vibrations that can occur with plastic inserts after several sessions of intense running.

In club racing or more demanding setups, this type of detail makes a difference: a poorly fixed or slightly eccentric crown generates noise, premature pinion wear, and loss of efficiency in transmission. The aluminium resolves this issue at its root.

Compatibility and Installation

This crown is designed exclusively for Slot.it Offset pods. It is not interchangeable with Sidewinder or Anglewinder pods: the gear geometry and motor position differ between configurations, and using the wrong crown causes incorrect alignment with the pinion, accelerating wear on both parts and reducing performance.

The reference axle is 2.38 mm, a standard commonly used in Slot.it rear ends. Before installing it, it is advisable to check that the axle shows no wear or ovalisation in the housing area, to ensure a clean fit of the aluminium insert.

Installation and Preparation

Installation does not require special tools, but it does require some attention: make sure to align the crown correctly with the motor pinion before permanently fixing the pod. A small variation in the tooth spacing can generate noise and accelerated wear. Ideally, turn the axle by hand after installation and check that the meshing is smooth and without any tight spots in any position.

If you are preparing the car for competition, also check that the crown is perpendicular to the axle and has no lateral play. Slot.it manufactures these parts with very tight tolerances, but a bent axle or a pod with play can negate that original precision.

Common Mistakes

• Trying to use this crown on a non-Offset pod: it is not compatible and the meshing will not be aligned.
• Forcing the aluminium insert onto an axle with a diameter different from 2.38 mm.
• Not checking the alignment of the pinion after installation, which can lead to premature wear.
• Confusing the inline configuration with Sidewinder or Anglewinder when selecting the pod and crown.

Frequently Asked Questions

Can I use this crown on a Slot.it Sidewinder pod?

No. This crown is designed exclusively for Offset pods with an inline motor configuration. Sidewinder pods have a different geometry and require their own specific crowns.

What advantage does the aluminium insert have over plastic?

Aluminium offers greater rigidity and a firmer grip on the axle, reducing play and vibrations during driving. In long sessions or in competition, the difference in consistency and durability is noticeable.

Which pinions is this 26-tooth crown compatible with?

The crown is compatible with standard Slot.it pinions for Offset inline configuration. The choice of the number of teeth on the pinion will determine the final gear ratio: more teeth on the pinion means higher top speed; fewer means more acceleration.

Is it necessary to use glue to secure the crown to the axle?

The aluminium insert is designed for a precise fit without the need for adhesive under normal conditions. However, some preparers choose to apply a minimal amount of axle adhesive in competition to ensure total immobility of the part under stress. Check the manufacturer's recommendations before doing so.

Is this crown included in any Slot.it kit or sold separately?

The reference SIGO26-AL corresponds to a spare or upgrade part sold independently, intended for those who want to replace or upgrade the crown of their rear end.

The Slot.it SIGO26-AL is a 26-tooth inline Offset crown with aluminium insert, compatible with 2.38 mm axles. Designed exclusively for inline motor configurations mounted on Offset pods, it delivers precise gear meshing and solid axle grip for club racing and performance slot car builds. A reliable upgrade for any Slot.it inline setup.
