Hydraulic rear air suspension Mercedes Mercedes GLS models 2016-2026 HIGHROAD

Hydraulic rear balloon American manufacturing Mercedes GLS (2016-2026) | HIGHROAD reinforced engineering Prepare the stability and royal comfort for your Mercedes car with the rear air suspension balloon (Air Spring) from HIGHROAD. This balloon is designed with high-density engineering rubber to withstand the heavy weights of GLS cars with 7 seats, making it the ideal and most reliable alternative to the original part. Your investment in HIGHROAD quality protects you from time losses and repeated installation costs of poor Chinese parts that quickly collapse under weight and heat pressure. 🚗 Precise compatibility (Fitment): Mercedes GLS-Class: X166 model (2016-2019 models). Mercedes GLS-Class: entirely new X167 model (2020-2026 models). Models: compatible with all engines (GLS450, GLS500, GLS580, GLS63 AMG) equipped with Airmatic system. 🛠️ Technical tips (HIGHROAD installation protocol): Assist check: ensure the oil assist is intact; damaged assist causes violent vibrations that tear the new balloon fibers and shorten its lifespan. Cleaning the mounts: the upper and lower balloon bases must be thoroughly cleaned from dust and salts to prevent microscopic holes caused by constant friction. Weight alert: do not lower the car from the lift with the balloons completely empty; the system should be partially filled with air first via the diagnostic device or by running the car while lifted partially to avoid improper rubber folding and explosion. Pair replacement: to ensure chassis balance and ADS+ system stability, it is always preferable to change the rear balloons as a pair (right and left) to ensure uniform sensor response and prevent car tilt.
