28 teeth, M2 hex screw, lightweight plastic, 16mm

Slot.it 28-tooth Crown Gear: lightweight plastic, M2 hex screw and 16 mm diameter

In the world of competitive slot racing, the transmission is one of the most delicate adjustment points. The SIGA1628-LPL crown gear from Slot.it offers 28 teeth made from lightweight plastic, secured with an M2 hex screw and a diameter of 16 mm. A component designed with the engineering philosophy that characterises the Italian brand: dimensional precision and attention to detail that is noticeable on the track.

Main Features

• Number of teeth: 28
• Diameter: 16 mm
• Material: lightweight plastic
• Fixing system: M2 hex screw
• Reference: SIGA1628-LPL
• Brand: Slot.it

Function and Performance

The crown gear is the final link in the transmission chain: it receives the motion from the motor pinion and transfers it to the rear axle. A well-chosen crown gear — in terms of number of teeth, diameter, and material — can make the difference between a car that pushes through the corner and one that falls short on the straight.

The lightweight plastic reduces rotating mass, resulting in a more agile response to acceleration changes. In technical circuits with many corners and frequent accelerations, this advantage becomes apparent. Combined with the precise adjustment of the M2 hex screw, the assembly remains firm without adding unnecessary weight to the setup.

Compatibility and Installation

This crown gear is designed for the Slot.it spare parts ecosystem, intended to work in conjunction with the pinions and axles of the same brand. The M2 hex screw allows for a clean adjustment with the appropriate tool, preventing the crown gear from shifting laterally during operation.

Before installation, it is advisable to check that the alignment with the pinion is correct: even minimal misalignment can cause vibration, premature wear, and loss of efficiency. Slot.it includes in its catalogue the necessary tools and spacers for precise installation.

When to Choose 28 Teeth?

The choice of the number of teeth on the crown gear depends on the gear ratio sought with the chosen pinion. A 28-tooth crown gear with a lower tooth pinion offers a moderate reduction ratio, suitable for medium-high speed circuits where a balance between acceleration and top speed is desired. To fine-tune the setup, it is recommended to test different pinion/crown combinations according to the specific characteristics of the track.

Frequently Asked Questions

Which pinions is this crown gear compatible with?

This crown gear is designed within the Slot.it ecosystem and is compatible with the pinions of the same brand that fit the corresponding module. Consult Slot.it's technical documentation or our team to confirm the specific combination according to your motor and axle configuration.

What advantage does lightweight plastic offer over other materials?

Lightweight plastic reduces the rotating inertia of the drivetrain, improving the car's response during acceleration and braking. It is a highly valued option in competition where every gram and millisecond counts.

Do I need any special tools to install this crown gear?

The fixing is done with an M2 hex screw, so you will need an M2 Allen key. It is important not to overtighten to avoid damaging the plastic or the axle.

Is this crown gear suitable for SPORT or UNIVERSAL track?

The crown gear itself does not depend on the type of track, but on the mechanical configuration of the chassis (motor, axle, pinion). Slot.it typically works with SPORT track (Scaleauto, Slot.it), but the crown gear is an internal transmission component of the car.

Is it recommended for recreational use or only for competition?

It can be used in both contexts. In recreational use, you will hardly notice differences with other materials, but if you are interested in fine-tuning your car's setup or participating in club championships, the choice of the right crown gear and pinion makes a real difference.

The Slot.it SIGA1628-LPL is a 28-tooth light plastic crown gear with M2 hex screw fixing and 16mm diameter, designed for precision slot car transmission setups. Compatible with Slot.it drivetrain components, this lightweight crown gear reduces rotational inertia for faster throttle response on technical circuits. An essential spare part for slot car racing enthusiasts and club competitors looking to fine-tune their gear ratio and overall performance.
