Our exclusive twin-tube damper designs are unique in the market, and some are rebuildable. In addition, the steel strut housings (front) are plated with a Mil-spec electroless nickel finish. Many of the components of the CS1 series systems are manufactured in the US and/or built in-house at our Placentia CA facility. Our Limited Warranty covers original purchaser for one year from the purchase date. Applications include Acura RSX 2002-2006, Civic 2001-2005, Civic 2006-2011
