The air suspension system for Mercedes GL | American engineering from HIGHROAD & FORMULA PLUS Get ready to restore the balance and calm of your Mercedes GL with the developed American hydraulic assistance kit (both sides). This product is designed to be a "completely new" and ideal replacement for models from 2016 to 2019, surpassing refurbished parts or Chinese alternatives that collapse under heavy loads, saving you time and repeated technician fees. ⚙️ Why choose HIGHROAD & FORMULA PLUS American assistance? Weight-bearing engineering: The hydraulic assistance is designed to match the large family size of the GL class, ensuring stability of the chassis and preventing "leaning" in turns. Heavy-duty air balloon: We use processed American engineering rubber to withstand high air pressure and road heat, preventing venting and protecting your car from sudden lowering. Airmatic system compatibility: The assistance is equipped with precise sensors that integrate with the car's computer to provide a smooth and comfortable driving experience that matches Mercedes' luxury. 🚗 Coverage and comprehensiveness: Front and rear axle: Fully new hydraulic assistance and sides (100% new). Models: Compatible with GL450, GL500, GL550, GL63 AMG from 2016 to 2019. 💡 Technical guidelines (American performance protocol): Quality versus cheapness: Choosing the American Formula Plus product is an investment that protects you from cheap parts that may damage the air compressor due to continuous work compensating for venting. Calibration: After installation, a "Calibration" process must be performed to ensure the vehicle is electronically leveled accurately from all four sides. Pair replacement: Always recommended to change the assistance as a set (front or rear) to ensure even air pressure distribution and extend the entire system's lifespan. ❓ Frequently Asked Questions: Q: Does the warranty cover popping sounds? A: Yes, the gold warranty for 6 months covers any manufacturing defects, including air leaks or abnormal noises. Q: Why is the American product more expensive than the Chinese? A: Because you are buying "peace of mind." Chinese and new parts wear out quickly and cost you twice in installation and removal fees, while our American product lasts longer and preserves your family's safety.
