56.5 x 2.38mm Evo

The Sideways EVO axle: precision at the service of tuning

The rear axle 56.5 x 2.38 mm EVO from Sideways (reference SWAX565, equivalent AX565) is one of those components that makes a difference on the workbench. With a diameter of 3/32" (2.38 mm) and a length of 56.5 mm, it is manufactured for those who leave nothing to chance in the preparation of their cars.

Each pack includes 2 units, allowing you to always have a spare on hand or equip two cars in the same preparation session.

Main features

• Diameter: 3/32" (2.38 mm), the most widely used standard in 1/32 scale slot racing.
• Length: 56.5 mm.
• Reference: SWAX565 / AX565.
• Contents: 2 units per pack.
• Line: EVO, the range of preparation spare parts from Sideways.

Function and performance

The rear axle is the component that transmits the rotation from the pinion to the wheels. A slight eccentricity, an irregular finish, or an incorrect length directly translates into vibration, loss of traction, and higher lap times. The Sideways EVO axle is designed to provide the straightness and surface finish necessary for smooth running and energy loss-free operation.

The length of 56.5 mm places it within the range typically used in 1/32 scale chassis with wide track or specific mounts, so it is advisable to always check the measurements of the receiving chassis before installation.

Installation and preparation

To get the most out of this axle, we recommend checking the alignment with a dial gauge or on a flat reference surface before installing it. A perfectly straight axle, combined with bearings in good condition and well-centred crowns, minimizes friction and improves acceleration response.

If you are going to use glue to secure pinions or crowns, apply just the right amount and ensure that the axle rotates freely in the bearings once dry. Any extra friction point will be felt on the straight.

Compatibility

As it is an axle with a diameter of 3/32" and 56.5 mm, it is compatible with setups that use this standard measurement. Sideways designs its EVO spare parts with its own chassis and models in mind, but compatibility with other market chassis that accept this diameter and length should be verified before installation. Do not assume compatibility: consult the technical documentation of your chassis or contact us if you have any doubts.

Frequently asked questions

What does "3/32" mean in the axle diameter?

It is a measurement expressed in fractions of an inch, very common in 1/32 scale slot racing. 3/32" is approximately 2.38 mm. It is the most widely used standard diameter for this type of spare parts.

Does this pack include one or two units?

The SWAX565 pack includes 2 units of the 56.5 x 2.38 mm EVO axle.

How do I know if this axle is compatible with my chassis?

You need to check two things: that the length (56.5 mm) fits the distance between the mounts of your chassis and that the diameter (3/32" / 2.38 mm) is what your bearings accept. If you have doubts, contact us before placing your order.

What bearings should I use with this axle?

Bearings with a 3/32" inner diameter. The most common in slot preparation are 3/32" x 1/4", although there are other options depending on the chassis. Check the specifications of your mount.

Can I use this axle in sidewinder and inline configurations?

Yes. The axle itself does not dictate the motor configuration: whether in a sidewinder setup (motor parallel to the rear axle) or inline (motor in line with the car), the rear axle is the same component. What varies is the position of the motor and the type of transmission (pinion/crown).

The Sideways EVO rear axle 56.5 x 2.38mm (SWAX565 / AX565) is a precision 3/32" slot car axle designed for 1/32 scale competition builds. This pack contains 2 units and is engineered for smooth rotation, minimal vibration, and consistent performance on track. An essential upgrade for serious slot car preparation enthusiasts.
