How to Install Strut Spacers in Your Subaru: Improve Handling and Performance in Your DIY Garage!

As a Subaru owner, you know that the suspension system is crucial for a smooth and comfortable ride. Whether you’re driving on highways, winding roads, or off-road trails, having a reliable suspension system can make a world of difference. If you’re looking to upgrade your Subaru’s suspension system, installing strut spacers can be an affordable and effective solution. In this article, we’ll provide a step-by-step guide on how to install strut spacers in your Subaru, and we’ll also cover some of the benefits of this upgrade.

What are Strut Spacers?

Strut spacers are small components that are installed on top of your Subaru’s strut assembly. They are designed to increase the distance between the strut assembly and the body of the car, which results in a lifted ride height. This lift can improve ground clearance, accommodate larger tires, and enhance handling and performance. Strut spacers are commonly used as a cost-effective solution for Subaru owners who want to upgrade their suspension system.

Choosing the Right Strut Spacer

The first step in installing strut spacers is selecting the right one for your Subaru model. Make sure to research online or contact a professional to confirm which strut spacer is best suited for your specific make and model. It’s essential to select strut spacers from a reputable brand, as low-quality spacers may lead to unwanted issues or premature wear and tear.

Tools Required

  • Brake cleaner
  • Strut spacers (make sure to have the correct sizes)
  • Threadlocker
  • Flat-head screwdriver

Note: Make sure to follow the instructions that come with your strut spacers, as some spacers may require additional tools or specific preparations.

Step-by-Step Instructions

  1. First, park your Subaru on a level surface and engage the parking brake. Then, loosen the lug nuts on the two front wheels.

  2. Using a hydraulic jack, lift the front of your Subaru, and place it on two jack stands. Be sure to place the jack stands on the proper and secure points underneath your vehicle.

  3. Now, remove the wheels from your Subaru using the lug wrench and socket wrench.

  4. Using the socket wrench, loosen the nuts that secure the top strut assembly mount.

  5. Once the nuts are loose, remove the top strut assembly mount and carefully set it down on a clean surface.

  6. Now, clean the top of the strut assembly mount with a brake cleaner to remove any dirt or grime that could cause issues when fastening the strut spacer.

  7. Install the strut spacer on top of the strut assembly mount. Position the spacer in line with the bolt holes and apply threadlocker to the mounting bolts. Secure the strut spacer using the torque wrench according to your manufacturer’s specifications.

  8. Once the spacer is secure, place the top strut assembly mount back in place and tighten the mounting nuts with the socket wrench.

  9. Finally, reinstall the wheels and lower your Subaru back to the ground. Tighten the lug nuts with the torque wrench according to the manufacturer’s specifications.

  10. Repeat these steps for the other side of your Subaru.
