Using the K - Tuned Spherical Tie Rod Set is easy. To adjust the length, just rotate the center bar either to the left or right. This will change the length of both sides at the same time. Remember, these tie rods are only for race use, so don't use them for regular daily driving. When installing, make sure to check compatibility with your vehicle model. The set is compatible with 01 - 05 Civic (ES1/EM2/EP3) and 02 - 06 RSX DC5, but won't work with BC Racing Extreme low. For maintenance, regularly check the bushings for wear. If you notice any signs of damage or excessive wear, replace the bushings right away. Our rubber bushings are stiffer than OEM and are designed to last, but proper care will extend their lifespan even more.
