Front shock absorber for Audi A4, A4, Quattro, A6, A6 Quattro, S4, S6, and Volkswagen Passat. Comfort suspension only. As a part of your suspension that takes a lot of abuse, a good set of shock absorbers will dictate the handling and ride of your car. In conjunction with coil springs, the shock absorber exists to dampen the bouncing motion of the coil spring. When a shock absorber fails, it will show signs of leakage in most cases, signalling that the gas/hydraulic interior seals have broken. To tell if your car needs shocks, walk to each corner and give it a strong push downward. The movement should not bounce up and down. If it bounces more than twice, the shock absorber is no longer dampening the movement of the spring. Typically, shocks last around 100k miles, but in some cases they can last far longer.
| COMFORT & PERFORMANCE Banded Piston: | Our engineered polymer piston band immediately responds to suspension movements even at slow speeds. The piston band effectively seals the working cylinder allowing the valves to operate at 100% efficiency. Valves with a banded piston can be finely tuned for specific vehicles to consistently provide the intended comfort and performance. |
| DURABILITY Micro-Polished Chrome Piston Rods: | SACHS micro-polished chromed piston rods have been hardened for maximum strength to provide the longest service life. Our chrome finish helps fight rust while the low-friction surface effectively prevents seal leakage. |
| ENDURANCE Polished Working Cylinder: | SACHS working cylinders are drawn to precise dimensions and polished ultra-smooth to prevent piston band wear. Our technology permits close tuning tolerances while reducing friction and heat for the utmost endurance. |
| OEM TECHNOLOGY Low Friction Seal: | SACHS advanced seal technology uses a special NBR rubber which is highly wear resistant and can withstand temperatures to 260 degrees F, keeping oil in and contaminants out. Engineered with low friction movement in mind, our design helps maintain the original tuning characteristics. |
| PRECISE TUNING Sintered Metal Valves: | Our high quality valve design enables precise oil flow by using sintered metal valve construction. Tight tolerances and strength from sintered metal allow for precise tuning of compression and rebound rates that restore the original handling dynamics. |
