As an RC car enthusiast, you know that having the right parts and accessories is crucial to getting the best performance out of your vehicle. One of the most important components of your RC car’s suspension system is the shock oil. In this article, we’ll explore everything you need to know about rc car shock oil, including its definition, why it’s important to use the right shock oil, and a brief overview of the article. By the end of this article, you’ll have a better understanding of how shock oil works and how to choose the right one for your RC car. So, let’s dive in!
Understanding Shock Oil

How Shock Oil Works
RC car shock oil is a type of fluid that is used to dampen the movement of the shock absorbers in your RC car’s suspension system. It works by providing resistance to the movement of the shock absorber’s piston, which helps to control the compression and rebound of the suspension. The viscosity or “weight” of the shock oil determines how fast or slow the shock absorber moves, which can have a significant impact on the handling and performance of your RC car.
Factors to Consider When Choosing Shock Oil
When selecting shock oil for your RC car, there are several factors to consider. The weight or viscosity of the shock oil is one of the most important factors to consider. The weight of the shock oil is usually measured in “wt” or “cst,” with higher numbers indicating thicker oil. The weight of the shock oil you choose will depend on the type of RC car you have, as well as your personal driving preferences.
Another factor to consider when choosing shock oil is the brand and quality. It’s important to choose a reputable brand that has a proven track record of producing high-quality shock oil. Cheaper, low-quality shock oil may not perform as well and could even damage your RC car’s suspension system.
Different Types of Shock Oil
There are several different types of shock oil available on the market, each with its own unique properties and characteristics. Some of the most common types of shock oil include silicone oil, mineral oil, and synthetic oil. Silicone oil is the most popular type of shock oil and is known for its consistency and stability. Mineral oil is a less expensive option that is often used by beginners, while synthetic oil is a more advanced option that provides high performance and durability.
Benefits of Using RC Car Shock Oil
When it comes to improving the performance of your RC car’s suspension system, using the right shock oil can make all the difference. Here are some of the benefits of using RC car shock oil:
Improved Suspension Performance
Using the right shock oil can significantly improve your RC car’s suspension performance. Shock oil helps to absorb shocks and vibrations from the road, providing a smoother ride and better handling. It also helps to prevent bottoming out, which is when your RC car’s suspension fully compresses and hits the ground, causing damage to the car and affecting its overall performance.
Better Handling and Control
In addition to improving suspension performance, using the right shock oil can also improve your RC car’s handling and control. With the right shock oil, your car will be more responsive to your steering and braking, allowing you to make sharper turns and stop more quickly. This can be especially helpful when racing or navigating tight corners.
Increased Durability of Shocks
Finally, using the right shock oil can also increase the durability of your RC car’s shocks. Shock oil helps to lubricate the shock absorbers, reducing friction and wear and tear on the shocks. This can help your shocks last longer and save you money in the long run by avoiding costly replacements.
Overall, using the right RC car shock oil can have a significant impact on your car’s performance, handling, and durability. In the next section, we’ll explore how to choose the right shock oil for your RC car.
How to Choose the Right RC Car Shock Oil
Choosing the right shock oil for your RC car can be a daunting task. With so many options available on the market, it can be challenging to know where to start. In this section, we’ll explore three key factors to consider when choosing the right shock oil for your RC car.
Weight and Viscosity
One of the most critical factors to consider when selecting shock oil is the weight and viscosity. Generally, shock oil comes in different weights, ranging from 10wt to 100wt or more. The weight of the shock oil determines how thick or thin it is, with a higher number indicating a thicker oil. The viscosity of the oil determines how quickly it flows through the small holes in the shock piston. A thicker oil will result in a slower rebound and compression, while a thinner oil will provide a faster response.
Brand and Quality
The brand and quality of the shock oil you choose can also have a significant impact on the performance of your RC car’s suspension system. It’s essential to choose a reputable brand that has a proven track record of manufacturing high-quality shock oil. The quality of the oil will determine how consistent and reliable it is, which is crucial for achieving optimal performance and durability.
Compatibility with Your RC Car’s Shocks
Lastly, it’s essential to choose a shock oil that is compatible with your RC car’s shocks. Different types of shocks may require different types of oil, and using the wrong oil can cause performance issues or damage to your RC car’s suspension system. It’s essential to check your RC car’s manual or speak with a knowledgeable RC car expert to determine which type of oil is best suited for your shock system.
By considering the weight and viscosity, brand and quality, and compatibility with your RC car’s shocks, you’ll be able to choose the right shock oil for your RC car’s suspension system and achieve optimal performance.
How to Change RC Car Shock Oil
If you notice that your RC car’s suspension isn’t performing as well as it used to, it might be time to change the shock oil. Changing shock oil is a simple process that can improve your RC car’s handling and control. Here’s what you’ll need and the step-by-step process for changing your RC car’s shock oil.
Tools and Materials Needed
- Shock oil
- Shock pliers
- Screwdriver
- Cleaning cloth
- Container for old oil
Step-by-Step Process for Changing Shock Oil
- Remove the shocks from your RC car and use the shock pliers to compress the shock.
- Unscrew the top of the shock and carefully pour out the old oil into a container.
- Clean the shock with a cloth to remove any old oil residue.
- Fill the shock with the new oil, making sure to use the proper weight and viscosity for your RC car.
- Reattach the top of the shock and repeat the process for the remaining shocks.
- Once all shocks are filled with new oil, reinstall them on your RC car.
Tips for Maintaining Your RC Car’s Shocks
- Check your shocks regularly for leaks or damage.
- Clean your shocks after each use to prevent buildup of dirt and debris.
- Use the proper weight and viscosity of shock oil for your RC car.
- Change your shock oil regularly to maintain optimal performance.
By following these simple steps, you can improve the performance of your RC car’s suspension system and keep it running smoothly. Remember to check your shocks regularly and change the oil when necessary to ensure the longevity of your RC car.
