Offset line crown 24Z aluminium insert

Slot.it 24-tooth crown gear with aluminium insert for Offset pod

The SIGO24-AL crown gear from Slot.it is a transmission component developed for inline motor installations with an Offset pod. Its aluminium insert ensures a solid attachment to the 2.38 mm rear axle and precise centring, critical factors when seeking consistency in transmission and lap times.

Technical specifications

• Number of teeth: 24Z
• Insert: aluminium
• Compatible axle diameter: 2.38 mm
• Motor configuration: inline with Offset pod

Function and performance

With 24 teeth, this crown gear offers a transmission ratio aimed at balancing acceleration and top speed, ideal for mixed-layout circuits where both corner exit and long straights must be considered. The aluminium insert, compared to plastic ones, reduces play and improves durability under repeated loads, particularly appreciated during long practice sessions or club championships.

Compatibility and installation

This crown gear is designed exclusively for use with Offset pod in inline configuration. It is not interchangeable with Sidewinder or Anglewinder setups. Before installation, it is advisable to check that the motor pinion it will be paired with is compatible in pitch and module with the crown gears from the Slot.it line, to ensure clean meshing and vibration-free operation.

The 2.38 mm axle is the standard in Slot.it kits and chassis, allowing for direct fitting in the vast majority of their setups without the need for additional adapters.

Common mistakes

• Using this crown gear in Sidewinder or Anglewinder configuration: it is designed solely for inline with Offset pod; the gear working angle is different.
• Not checking the tightness of the insert: although aluminium provides better grip than plastic, it is advisable to periodically check that the crown gear does not exhibit axial play after intense sessions.
• Mixing incompatible tooth pitches: always pair with the correct pinion from the Slot.it catalogue to avoid premature wear and transmission noise.

Frequently asked questions

What is the difference between an aluminium insert and a plastic one?

The aluminium insert is stiffer and more resistant to deformation from heat and mechanical stress. This translates to less play over time and a cleaner transmission, especially important in cars with a certain level of tuning.

Can I use this crown gear in a Sidewinder setup?

No. The SIGO24-AL crown gear is specifically designed for inline motors with an Offset pod. For Sidewinder configurations, Slot.it offers specific references with appropriate gear geometry.

Which pinions is it compatible with?

It should be paired with pinions of the same pitch/module as those used in the Slot.it transmission line. Consult the Slot.it pinion catalogue to find the appropriate tooth combination for your target transmission ratio.

Is the 2.38 mm axle the standard in Slot.it kits?

Yes, 2.38 mm (equivalent to 3/32") is the standard rear axle diameter in the vast majority of Slot.it kits and chassis, allowing for direct installation in those setups.

How many teeth is recommended for club circuits?

It depends on the motor pinion and the length of the circuit. A 24Z crown gear combined with a pinion of between 9 and 11 teeth usually provides a versatile transmission ratio for medium-length tracks. Adjust according to your motor characteristics and the maximum speed of the longest section of the track.

The Slot.it SIGO24-AL is a 24-tooth inline Offset crown gear featuring an aluminium insert, compatible with 2.38 mm axles. Designed exclusively for inline motor configurations with Offset pod, it delivers precise and durable power transmission for slot car racing. A key upgrade part for Slot.it chassis builds seeking consistent lap times and reduced drivetrain play.
