MXL z67 2 mm Belt: Clean and Precise Transmission for Your 1/32 Slot Car Build

When belt transmission is the chosen option for a 1/32 slot car chassis, every detail matters: the pitch, the number of teeth, and the width directly affect track performance. This MXL pitch, 67 teeth, and 2 mm wide belt from Mitoos is designed to provide a perfect fit with its entire range of toothed pulleys, without play or vibrations that could hinder the car's response.

Function and Performance

MXL pitch toothed belts are the benchmark in precision transmissions for slot cars for several reasons:

• The toothed design prevents slipping that smooth belts suffer from, ensuring a constant and predictable gear ratio.
• They operate without oil or lubrication, keeping the chassis clean and reducing maintenance between sessions.
• The flexibility of the material absorbs micro-vibrations from the motor, contributing to a smoother drive.
• The 2 mm width is suitable for compact builds where lateral space is limited.

Compatibility

This belt fits precisely with the complete range of Mitoos toothed pulleys:

• Nylon pulleys (Ref. M136–M140): lightweight and quiet, ideal for builds focused on smooth operation.
• Aluminium pulleys (Ref. M143–M149): greater rigidity and durability, common in more demanding competition setups.

The MXL pitch is a standardised specification, so it may also be compatible with other market pulleys that respect this pitch and number of teeth; however, we always recommend checking the fit before use in competition.

Installation and Preparation

Installing a toothed belt on a slot car chassis requires attention to tension: an overly tight belt generates friction and wears out the pulleys, while a loose belt causes tooth skipping and loss of traction. A common trick among builders is to adjust the tension until the belt gives slightly when pressed with a finger, without being slack.

It is supplied with 1 unit per order. For competition builds, it is advisable to always have a spare unit, as belts are consumables that wear out with use.

Common Mistakes

• Mixing different pitches: an MXL belt is not interchangeable with GT2, HTD, or other pitches. Always verify that the pulley is MXL.
• Ignoring the width: this reference is 2 mm. Mitoos also offers the same belt in 2.3 mm (ref. CXM467 or equivalent). Choose the width that corresponds to your pulley and chassis.
• Tightening cold on an adjusted chassis: the heat generated during the race can slightly expand the belt; calibrate the tension with the car at working temperature if possible.

Frequently Asked Questions

How many units does this product include?

This item includes 1 unit of the MXL z67 2 mm wide belt.

Is it compatible with pulleys from other brands?

The MXL pitch is standardised, so it can generally work with any MXL pitch pulley with 67 teeth. However, compatibility is guaranteed with the Mitoos range of toothed pulleys (nylon M136–M140 and aluminium M143–M149). For other brands, it is advisable to check the fit before using it in a race.

What is the difference between the 2 mm and 2.3 mm versions?

The width affects the contact area with the pulley and the available space in the chassis. The 2 mm version is narrower and fits into more compact builds; the 2.3 mm version offers slightly more traction surface. Both are MXL pitch and 67 teeth, so the choice depends on your chassis design and the pulley you use.

How often should the belt be changed?

It depends on usage and mounting conditions. In regular competition, it is advisable to check the belt after each intense session and replace it at the first sign of stretching, cracks, or wear on the teeth. Always keeping a spare unit is good practice.

Can the belt be lubricated?

It is neither necessary nor recommended. MXL toothed belts operate dry; applying lubricant can attract dirt, accelerate tooth wear, and cause unwanted slipping.

The Mitoos MXL z67 2mm toothed belt (ref. CXM467) is a precision 1/32 slot car drive belt compatible with the full range of Mitoos toothed pulleys, both nylon (M136–M140) and aluminium (M143–M149). Designed for smooth, slip-free power transmission in slot car builds, this normalised MXL-pitch belt is a reliable choice for club racing and competitive slot car preparation.
