58.5 x 2.38mm Evo

The Sideways EVO axle: precision in the rear end, lap after lap

Sideways has been a benchmark in the world of competitive slot racing for years, and its EVO spare parts line adheres to that same philosophy: components designed for tuners and drivers who leave nothing to chance. The axle 58.5 x 2.38 mm (3/32) with reference SWAX585 is a fundamental component to ensure that the transmission operates with the adjustment and concentricity that track performance demands.

Main features

• Length: 58.5 mm
• Diameter: 2.38 mm (3/32")
• Line: Sideways EVO
• Pack contents: 2 units
• Reference: SWAX585 / AX585

Function and performance

The rear axle is one of the most critical elements of a slot car's mechanical assembly. An axle with play, bent, or with uneven wear transmits vibration, penalises traction, and compromises the lifespan of the crown gear and tyres. The Sideways EVO line addresses this issue with axles machined to tight tolerances, designed to fit cleanly into competition brackets and hubs.

The format of 2 units per pack is particularly practical in active tuning contexts: it allows for an immediate spare axle in case of a breakage during a tuning session or competition.

Compatibility and installation

This axle is designed for applications requiring the standard diameter of 3/32" (2.38 mm), common in a wide variety of competitive slot car chassis. Before installation, it is advisable to verify the appropriate length for the specific car bracket and ensure that the hubs used are compatible with this diameter. Careful installation, with the crown gear well centred and the tyres seated symmetrically, makes a difference in the car's response.

Common mistakes

• Installing the axle without checking concentricity: a slightly off-centre axle in the bracket generates vibration even at low speeds.
• Reusing a bent axle: after any strong impact, it is preferable to replace it. A damaged axle ruins the behaviour of the rear end even if it visually appears straight.
• Not verifying the length before purchase: ensure that 58.5 mm is the correct measurement for your chassis and bracket.

Frequently asked questions

What does the 3/32 format mean?

It is the measurement in inches of the axle diameter, equivalent to 2.38 mm. It is one of the most common diameters in competitive slot cars and is compatible with a wide variety of brackets and hubs on the market.

Why does the pack include 2 units?

Having two axles allows for an immediate spare unit for tuning sessions or competition, and also facilitates comparing wear between used and new axles during car preparation.

How do I know if I need to replace the axle?

The most common symptoms are abnormal vibration while running, uneven tyre wear, or lateral play in the bracket. When in doubt, a quick check with a dial gauge or simply rolling the axle on a flat surface can detect deviations.

Is it compatible with any slot bracket?

It is compatible with brackets designed for axles with a diameter of 3/32" (2.38 mm) and a length of 58.5 mm. We recommend verifying these measurements against your chassis specifications before placing an order.
