Using these K - Tuned compliance bushings is easy. First, make sure your car is parked on a flat and stable surface. Then, carefully remove the old bushings from your car's suspension system. Next, install the new K - Tuned bushings in the same place where the old ones were. It's important to ensure that they are properly aligned and tightened. When it comes to maintenance, regularly check the bushings for any signs of wear or damage. If you notice any cracks or excessive wear, it's time to replace them. Also, keep the bushings clean to prevent dirt and debris from causing premature wear. And remember, these bushings are designed for the 2006 - 2011 Civic Si, so don't use them on other car models.
