How to Change the Front Strut Assemblies on Your 2006 to 2011 Honda Civic Si

Your Honda Civic’s front struts work as a structural component to absorb energy from the suspension system, preventing excessive movement when driving. Removing and replacing faulty or worn struts can improve the overall ride and comfort of your 2006 to 2011 Honda Civic Si, since struts can affect the handling, braking, tire wear, and alignment of your car. Struts can wear or deteriorate from high heat and weather, and failing struts should be changed to prevent tire or suspension damage. It’s recommended that you inspect your Civic’s struts every 50,000 miles, and they should always be replaced in pairs since they have experienced the same amount of wear. Replacing your Civic’s struts with complete strut assemblies can also help ensure that all the parts of the strut are within specification and working together at their best. Our detailed instructions and educational video can help you perform a front strut replacement on your 2006 to 2011 Honda Civic Si.
