Upgrade Your RC Car Performance with HobbyPark Metal 5mm Shim Washers – 100-Pack

What is an RC Car Axle Shim?

An RC car, also known as a remote-controlled car, is a popular type of hobby vehicle that can be maneuvered using a remote control. These miniature vehicles come in various types and models, offering enthusiasts an exciting experience of driving and racing.

One crucial component of an RC car is the axle. The axle is responsible for connecting the wheels to the chassis, allowing the wheels to rotate freely. However, sometimes the axle might not fit perfectly into the wheel, causing a small gap that can lead to wobbling or poor performance. This is where an RC car axle shim comes into play.

An RC car axle shim is a thin, flat piece typically made of metal or plastic that is used to fill the gap between the axle and the wheel. By inserting a shim, you can effectively eliminate the wobbling, resulting in a smoother and more stable performance of your RC car.

The Importance of Axle Shims in RC Cars

Axle shims play a crucial role in optimizing the performance of RC cars, especially in terms of stability and handling. Here are a few key reasons why RC enthusiasts often use axle shims:

1. Improved Stability: Axle shims ensure a snug fit between the axle and the wheel, reducing any wobbling or play. This results in enhanced stability, especially when cornering or navigating uneven terrains.

2. Enhanced Handling: RC car enthusiasts are always seeking better control and handling. Axle shims contribute to improved handling by minimizing any unwanted movement or vibrations, allowing for smoother and more precise steering.

3. Tire Wear Reduction: Wobbling caused by an imperfect axle fit can result in uneven tire wear. By using axle shims, you can significantly reduce tire wear and prolong the lifespan of your RC car’s tires.

4. Performance Optimization: An RC car that performs optimally is every enthusiast’s dream. Axle shims help fine-tune the performance of the RC car by eliminating unnecessary movement, ensuring that the power from the motor is efficiently translated into motion.

Types of RC Car Axle Shims

When it comes to RC car axle shims, there are various options available to cater to different needs and preferences. Here are some commonly used types:

1. Metal Shims: Metal shims are often made of aluminum or brass and are known for their durability and precision. These shims are suitable for high-performance RC cars that require maximum stability.

2. Plastic Shims: Plastic shims, usually made of nylon or polycarbonate, are lightweight and affordable. They are ideal for hobbyists who prioritize cost-effectiveness while still benefiting from improved stability.

3. Adjustable Shims: Some axle shims come with adjustable features, allowing you to fine-tune the fit according to your preferences. These shims provide flexibility and customization options for RC car enthusiasts aiming for precise adjustments.

How to Install an RC Car Axle Shim

Installing an axle shim is a straightforward process that requires minimal effort. Here’s a step-by-step guide to help you install an RC car axle shim:

1. Begin by removing the wheel from the RC car’s axle, taking note of any existing shims or spacers.

2. Place the axle shim onto the axle where it meets the wheel. Ensure that it sits flush against both the axle and the wheel.

3. Reinstall the wheel onto the axle, securing it firmly in place.

4. Repeat the process for each wheel, ensuring that all axles are properly shimmed.

5. Test the RC car’s performance to assess the improvement in stability and handling. Make any necessary adjustments if required.

Frequently Asked Questions

1. Can I use multiple axle shims for better stability?
Yes, you can stack multiple axle shims to achieve a tighter fit and improved stability. However, it’s essential to consider the space available between the wheel and the RC car’s chassis, ensuring that the stacked shims do not cause any clearance issues.

2. Do I need to remove the existing shims before installing new ones?
If your RC car already has shims or spacers, it’s recommended to remove them before installing new axle shims. This allows for a fresh installation, ensuring that the shims fit perfectly without any interference.

3. Can axle shims be used for all RC car models?
Axle shims are compatible with most RC car models, regardless of their scale or type. However, it’s always a good idea to check the specific requirements of your RC car’s manufacturer to ensure compatibility.

4. How do I choose the right size of axle shim for my RC car?
To choose the right size of axle shim, measure the diameter of your RC car’s axle and compare it with the available shim sizes. It’s crucial to select an axle shim that fits snugly without being too tight or loose.

5. Are axle shims a permanent modification to my RC car?
No, axle shims can be easily removed or replaced whenever necessary. They do not require any permanent modifications to your RC car, allowing you to adjust and fine-tune the fit as needed.


In conclusion, an RC car axle shim is a valuable accessory that helps optimize the performance of your RC car. By filling the gap between the axle and the wheel, axle shims enhance stability, improve handling, reduce tire wear, and fine-tune the overall performance of the RC car. Whether you choose metal or plastic shims, the installation process is simple, and the benefits are noticeable. Upgrade your RC car with axle shims, and enjoy a smoother, more stable driving experience.
