BILSTEIN Drag Series Shock Absorbers and Struts are designed specifically for cars that aren't towed to the strip, but are driven there on the street. These "Door Slammers," as they are often referred to, require a unique balance that allows the vehicle to perform at an extremely competitive level on the strip, while offering the comfort and control expected of a daily driver. With BILSTEIN's speed-sensitive, self adjusting monotube design and years of experience in motorsports tuning, BILSTEIN accomplishes this feat with the Drag Series Shocks and Struts.Learn More
