Bilstein SS4 Series Shock Absorbers are designed specifically with custom street rods in mind using Bilstein's patented gas pressure technology. These 36mm monotube shocks are hand built to insure that top level quality is achieved with every shock that goes out the door. Each shock is tuned digressively using Bilstein's proven deflective disc valving technology and are available in two off the shelf settings as well as a custom setting. The body has a high quality, triple plate chrome finish for easy maintenance and flashy good looks. The internal bore has been hard anodized to minimize wear caused by friction making these shocks extremely durable. The shock comes with dropped solid axle specific mounts (5/8 inch bottom 7/16 inch top) allowing for easy installation. The polyurethane bushing mounts have been impregnated with graphite, virtually eliminating the squeaking commonly associated with polyurethane, and are used top and bottom to promote a long life.
While the ThyssenKrupp Bilstein Company began as a German enterprise, Bilstein shocks are developed and manufactured in Hamilton, Ohio. Bilstein develops and fabricates premium quality monotube shock absorbers directly for automobile manufactures, aftermarket outfits and motorsports applications. The precision and craftsmanship in manufacturing that fueled company growth in Germany were brought straight to the factory in Hamilton, Ohio. The factory includes an engineering department, rigorous shock testing facility and a motorsports track. The track allows the engineers to tweak their designs in response to real world testing during development. The rigorous testing allows for designs to go through a machine simulated life of a shock absorber in all kinds of terrain conditions. The resulting products promise the highest in performance.
