62.5 x 2.38mm Evo

The Sideways Evo Rear Axle: Precision in Every Millimetre

When fine-tuning a slot car, the rear axle is one of the elements that most influences track behaviour. An axle with tight tolerances ensures that the transmission reaches the wheels cleanly, that bearing wear is uniform, and that the car's response is consistent lap after lap.

The 3/32 x 62.5mm Evo axle from Sideways (ref. SWAX625) comes in a pack of 2 units, designed for both the preparer who needs immediate replacement and for those who build several cars from the Sideways range and want to keep a stock of key components on hand.

Main Features

• Diameter: 3/32" (approx. 2.38 mm) — standard measurement in competitive slot cars.
• Length: 62.5 mm, specific to the EVO format from Sideways.
• Official Reference: SWAX625.
• Contents: 2 units per pack.

Function and Performance

The 3/32" diameter is one of the most widespread in competitive slot preparation. It allows the use of standard-sized bearings and is compatible with a wide variety of crown gears, pinions, and wheel hubs from the Sideways range. The length of 62.5 mm is designed to fit correctly in Evo chassis, providing the appropriate track width without the need for adaptations.

A well-maintained axle is the foundation upon which the crown gear, bearings, and rear wheels rest. Replacing it when vibrations, axial play, or uneven tyre wear appear is one of the most cost-effective maintenance interventions that can be made on a competitive car.

Compatibility and Installation

This axle is designed for the models in the Sideways Evo line. Before installing it, it is advisable to check that the available bearings and wheel hubs correspond to the 3/32" diameter. Installation does not require special tools: a wheel press or suitable mounting tool is sufficient to avoid damaging the bearings during assembly.

If you are going to use it in a new build, take the opportunity to also check the alignment of the guide and the height of the chassis, as a perfectly centred axle only delivers its full performance when the assembly is well adjusted.

Common Mistakes

• Installing the axle without checking that the bearings are clean and free of play: even if the axle is new, worn bearings negate its precision.
• Forcing the axle with inappropriate tools that may create marks or deformations in the bearing support areas.
• Confusing this length (62.5 mm) with other available lengths in the Sideways range: always check the reference before ordering.

Frequently Asked Questions

Which Sideways cars is this axle suitable for?

It is designed for the models in the Sideways Evo line. If you have doubts about whether it fits your specific car, consult the reference SWAX625 in the technical documentation of your model or contact us at Ministry of Hobby.

Does the pack include two axles or just one?

The pack contains 2 units of the 3/32 x 62.5mm Evo axle.

What bearings should I use with this axle?

Being 3/32" diameter, it is compatible with bearings that have an inner diameter of 3/32" (2.38 mm), which is the standard measurement in most competitive slot preparations. Check your chassis specifications to confirm the necessary outer diameter.

When should the rear axle be replaced?

It is most common to do so when vibrations appear at high speed, when axial play is detected, or when the rear tyres show uneven wear. It is also advisable to check it after hard impacts or falls of the car.

Is it compatible with crown gears and hubs from other brands?

In principle, any component designed for a 3/32" axle should be dimensionally compatible. However, to ensure optimal fit and expected performance, we recommend using components from the Sideways Evo range.

The Sideways SWAX625 is a 3/32 x 62.5mm Evo rear axle for slot car racing, sold in a pack of 2 units. Designed for Sideways Evo chassis, this precision axle ensures perfect alignment, smooth power transfer and consistent lap times. A key maintenance component for competitive slot car builders looking for reliable drivetrain performance. Available at Ministry of Hobby.
