The "Hero" in suspension systems: Mercedes assistance W221 Panorama | American engineering from HIGHROAD & FORMULA PLUS Get your car's "yacht" comfort ready with the most requested and reliable product. This set of hydraulic assistance (side supports) is specially designed to be compatible with models from 2006 to 2013, making it the perfect alternative for owners of S300, S350, S500, S550 who are looking for durable American quality. ⚙️ Features of HIGHROAD & FORMULA PLUS assistance: Completely new 100%: internal valves with a long lifespan compared to remanufactured ones. Superior American engineering: high-density rubber withstands summer temperatures without cracking. Silent stability: shock absorption technologies eliminate vibrations and ensure cabin quietness. 🛠️ Golden tips to extend the lifespan of hydraulic assistance: Based on our experience, follow these steps to keep the assistance in factory condition for as long as possible: Continuous movement protocol: hydraulics "die" with long stops. Avoid leaving the car parked for more than a week; movement helps lubricate internal valves and maintain the flexibility of the air balloon from drying or hardening. Avoid rough roads at high speeds: Although the American assistance is strong, sudden bumps at high speeds increase internal air pressure inside the balloon dramatically, which may weaken the rubber fabric over time. Regular cleaning: Be sure to wash the "rubber parts" of the assistance from below with fresh water to remove salts and stuck dirt; accumulated dirt acts as a "sander" that accelerates wear of the rubber when the assistance expands and contracts. Change the assistance mounts: If you feel vibrations, check the mounts; a damaged mount causes uneven pressure on the shock absorber shaft and leads to early damage. 💡 Important technical instructions (during installation): Digital calibration: a "Reset" and height level calibration via computer are necessary to ensure even pressure distribution. Compressor check: ensure the compressor is pumping air strongly enough; weak pressure makes both sides work with double effort. Double replacement: always recommended to replace the assistance as a set for one axle to ensure the car's "stand" stability. ❓ Frequently Asked Questions: Does it fit the S500 4Matic?
