When it comes to optimizing the performance of your RC car, paying attention to the finer details, like shock oils, can make a significant difference. Your RC car's shocks and suspension play a crucial role in maintaining control, stability, and responsiveness during your thrilling races or bashing sessions. In this beginner's guide, we'll delve into the world of RC cars shock oils, understanding their importance, the different weights available, and how to choose the right oil to enhance your RC car's performance.
RC Car Shocks and Suspension
The shocks and suspension of your RC car are critical components that determine how well your vehicle handles various terrains, jumps, and turns. They help absorb impacts, maintain tire contact with the ground, and keep your car balanced. To achieve optimal performance, it's essential to ensure that your shocks are properly tuned and maintained. This is where shock oils come into play.
Why You Need Oil in Shock Absorbers
Shock absorbers, commonly referred to as shocks, require oil to control the movement of the suspension arms. The oil inside the shocks provides damping, preventing them from rebounding too quickly and maintaining a smooth ride. The viscosity or thickness of the shock oil determines how fast the shock rebounds after being compressed. This allows you to fine-tune your RC car's handling characteristics to match your driving style and the terrain you're racing on.
Different Weights of Shock Oil
Shock oils are available in a range of weights, each influencing how your RC car's suspension behaves. The weight of shock oil is typically measured in viscosity units, often denoted by "wt." Understanding the different weights and their effects can help you fine-tune your RC car's performance to match your driving style and track conditions.
- 10wt - 20wt: These are very light shock oils suitable for smooth tracks or tracks with minimal bumps and jumps. They provide quick rebound, making your RC car responsive and nimble. These weights are commonly used in on-road racing where precise handling is crucial.
- 25wt - 35wt: These shock oil weights offer a balance between responsiveness and stability. They are versatile options that work well on a variety of tracks, from moderately smooth to slightly bumpy terrains. These weights are often considered as a starting point for many RC car setups.
- 40wt - 45wt: Medium-weight shock oils provide a compromise between stability and agility. They are suitable for tracks with moderate bumps and jumps. These weights offer a good balance of control and quick response, making them popular choices among both beginner and experienced RC car enthusiasts.
- 50wt - 60wt: Heavier shock oils are designed for rough terrains and tracks with significant jumps and bumps. These oils offer slower rebound, ensuring better stability and control over uneven surfaces. They help prevent your RC car from bottoming out on rough landings and provide better traction.
- 70wt and above: These are extremely heavy shock oils intended for very rough tracks or heavy RC vehicles. They slow down the rebound significantly, providing the highest level of stability and control. These weights are commonly used in monster trucks and vehicles designed for extreme off-road conditions.
Picking The Right Shock Oil
Selecting the appropriate shock oil for your RC car involves considering several crucial factors. Each of these factors influences how your car's suspension behaves on the track, allowing you to tailor its performance to your driving style and the terrain you're racing on. Here are the key factors to take into consideration when choosing the right shock oil:
- Track Conditions: The nature of the track plays a significant role in determining the ideal shock oil weight. For smoother tracks, such as on-road circuits, lighter shock oil weights like 10wt to 25wt offer quicker response. On rougher off-road tracks, heavier shock oils like 40wt to 60wt provide better stability and control.
- Driving Style: Your driving style impacts how your RC car handles different terrains. If you prefer aggressive and high-speed driving, a slightly heavier shock oil might help prevent the car from bottoming out during jumps. For more technical tracks with tight turns, a lighter shock oil can improve agility.
- Vehicle Weight: The weight of your RC car affects how it interacts with the track surface. Heavier vehicles may benefit from slightly heavier shock oils to maintain stability, while lighter vehicles can make use of lighter oils for quicker response.
- Suspension Setup: The overall suspension setup, including spring rates and shock mounting positions, should complement your chosen shock oil. Adjustments to these components, along with the shock oil weight, can create a harmonious balance between stability, agility, and traction.
- Terrain: Consider the type of terrain you'll be racing on. Is it a smooth, high-grip track, or a bumpy, loose surface? Adjust your shock oil accordingly to ensure your RC car can handle the specific challenges of the terrain.
- Experience Level: If you're a beginner, starting with a medium-weight shock oil like 30wt to 40wt is a safe choice. As you gain experience and confidence, you can experiment with different shock oil weights to fine-tune your setup.
- Manufacturer Recommendations: Always refer to your RC car's manual for manufacturer recommendations on shock oil weights. These guidelines provide a valuable starting point based on the manufacturer's testing and intended use of the vehicle.
- Trial and Error: RC car setup is often a process of trial and error. Start with a shock oil weight that matches your initial assessment, and then make incremental adjustments during practice sessions. Observe how your RC car responds to changes and gather feedback to determine the most effective setup.
Incorporating these factors into your decision-making process will help you pick the right shock oil that aligns with your RC car's setup and your desired performance outcomes. Remember that finding the perfect shock oil weight may take some time and experimentation, but the results can significantly enhance your driving experience and make you a more competitive racer on any track.

I'm trying to replace some shock absorbers on a bush aircraft landing gear setup. What oil weight would you recommend for extreme rough Landings on rough surfaces for an 8 lb airplane.Thanks!

It would depend on if you are using springs with the shocks and the number of holes in the shock pistons but the weight would be somewhere between 40wt and 65wt.
