Eibach 12" Coil-Over Spring - 2-1/2" I.D. - 650 lb. HSXSM11SASPA The top trailing edge ofEibach uses the world's finest quality, chrome silicon steel wire to produce coil springs with maximum travel and minimum weight. Eibach Springs are metric sized and, therefore, not limited to the SAE sized wire used in the production of many of the springs currently on the market. Eibach Springs are cold formed on CNC machinery, insuring precise tolerances on spring rates and free height, as well as longer life expectancy. Eibach Springs are heat
