Remove Old Shocks

Once you’ve gathered all your tools and materials, you can start removing the old shocks. Here are some simple steps that you can follow:

  1. Remove the wheels: To access the shocks, you need to remove the wheels first. You can use a wrench to take the wheel nuts off.
  2. Unscrew the shock at the bottom: Locate the bottom of the shock and remove the nut that is holding it in place.
  3. Unscrew the shock at the top: Find the top of the shock and remove the screw that connects it to the car frame.
  4. Remove the old shock absorber: Carefully remove the old shock absorber and dispose of it properly.

Make sure that you have a container to catch any oil that may spill out of the shock absorber. It’s important to keep the parts organized as they come off the car to ensure that you can easily find them later for reassembly.

Interesting Fact:

Did you know that the function of shocks on an RC car is to absorb shock and vibrations, which helps to keep the car’s wheels in contact with the ground for more extended periods? Optimal performance is achieved when shocks are appropriately installed and maintained.

If any of the screws or nuts are damaged or rusty, it’s a good idea to replace them with a new one during reassembly. There are various online stores you can visit to purchase spare parts for your RC cars such as Amazon, HobbyPartz, and eBay. Here is a table of the top online stores that you can buy RC car parts from:

How do you remove old shocks?

To remove old shocks, follow these steps:

  • Loosen the lug nuts on the wheel where the shock is located.
  • Use a jack to lift the car and support it with jack stands.
  • Remove the wheel.
  • Remove the bolts that attach the shock to the suspension.

For more detailed information or if you need replacement shocks, check out automotive repair websites or product pages for shock absorbers.

Install New Shocks

Now that you’ve removed the old shock absorber, it’s time to install the new one. Here are some steps to follow:

  1. Insert one end of the shock: Place the shock in its correct position, and attach it to the lower part of the suspension arm.
  2. Insert the other end: Insert the upper end of the shock through the mounting hole located in the chassis.
  3. Secure with the mounting screw: Keep the shock in place by tightening the mounting screw using a screwdriver.
  4. Check and adjust the length of the shock: Make sure the length of the shock is adjusted to match the other shocks on the car. It’s essential to ensure the height of the car is level, and all wheels touch the ground.

There are various shock absorbers in the market, from oil shocks to hydraulic shocks. You may choose to upgrade to high-performance shocks or purchase matching shocks specific to your driving style and terrain. Some RC car manufacturers have genuine spare parts available for purchase. Be sure to check with your manufacturer before buying any upgrade parts.

There are also various online resources where you can find step-by-step guides, including YouTube tutorials on how to change the shocks. You may also visit online forums and communities specific to RC cars such as RCTech and RCGroups, where experts and enthusiasts share tips and insights on maintaining and upgrading their RC cars.

What part of the car is the shock?

The shock absorber, also known as a shock, is part of a car’s suspension system. Its purpose is to absorb and dampen the movement of the springs when encountering bumps or vibration on the road. It helps to keep the car stable and reduce the impact of any bumps or obstacles that are encountered on the road.

For more information about car parts, check out websites such as AutoZone or O’Reilly Auto Parts. They have a wide range of products and accessories for your car.

Test the New Shocks

After installing the new shock absorbers, it’s crucial to test them to ensure they’re functioning properly. Here are some steps to follow:

  1. Take the RC car for a test drive: Drive your RC car around your backyard or a nearby playground to test how the new shock absorbers handle various terrains and speeds.
  2. Observe how your car handles: Check if your car can handle jumps and bumps smoothly, if the car is jumping too high, or if it’s bottoming out. Note if the car’s handling and steering have improved, if it’s more stable, or if there is noticeable body roll.
  3. Check for damage or leaks: Inspect the new shocks for any signs of leaks. Leaks mess with the damping and will decrease the effectiveness of the shocks. Also, check for any unexpected wear on the shock absorbents.

If there are any issues, double-check and re-adjust the shock absorbers. It’s essential to ensure that the shocks match and are installed correctly. If you need further help, you may visit your local hobby shop or reach out to online communities for advice.

In conclusion, changing shocks on an RC car is relatively easy as long as you take your time and follow the instructions carefully. Properly installed shock absorbers improve your RC car’s stability, handling and speed, enabling you to drive it better. Better driving means that you get more out of your RC car. Remember to maintain and upgrade your shocks regularly to prolong their lifespan and ensure optimal performance.

Maintenance and Upgrades

To keep your RC car’s shocks in good condition, proper maintenance and upgrading to high-performance shocks is essential. Here are some tips:


  • Regularly clean and lubricate the shocks to prevent wear and tear and ensure optimal performance.
  • Inspect the shocks before every use and replace any damaged parts as soon as possible.
  • Invest in a shock rebuild kit to make repairs more accessible, should a problem arise.


  • Upgrade to high-performance shocks to improve your driving experience significantly.
  • Choose shock absorbers that match your driving style and terrain (on-road or off-road driving).
  • Have an idea of what kind of shocks to use. For example, hydraulic shocks are great for on-road driving and air shocks for off-road driving. Some of the top-rated RC car shocks brands include Traxxas, Hobbypark, and GoolRC.
  • Get information from online forums, social media pages and hobby shops, to learn more about which shocks work best for your RC car.

By taking proper care of your RC car’s shocks and upgrading them when necessary, you’ll get the best driving experience possible. If you need help or advice, consult online resources or get in touch with industry professionals via social media or hobby shop websites.
