Hydraulic rear balloon Mercedes Mercedes ML models 2007-2015 HIGHROAD

Hydraulic rear air spring, American manufacturing, Mercedes ML (2007-2015) | HIGHROAD reinforced engineering. Prepare for stability and superior comfort for your Mercedes with the rear air suspension spring (Air Spring) from HIGHROAD. This spring is designed with high-density engineering rubber to withstand maximum pressure and hot weather conditions, making it the ideal and most reliable alternative to the original part in the ML categories, and it far exceeds cheap Chinese options that quickly deteriorate and cause repeated installation and removal costs. 🚗 Precise compatibility (Fitment): Mercedes ML-Class: W164 model (2007-2011 models). Mercedes ML-Class: W166 model (2012-2015 models). Categories: Compatible with all engines (ML350, ML500, ML550, ML63 AMG) equipped with the Airmatic system. 🛠️ Important technical tips (HIGHROAD installation protocol): Oil helper check: In Mercedes ML, the spring is installed next to the rear helper; ensure the helper is free of oil leaks, as a weak helper causes violent vibrations that damage the fibers of the new spring. Clean the mounts: The upper and lower spring bases must be thoroughly cleaned of dirt and salts to prevent microscopic holes caused by friction. Weight alert: Do not lower the car from the lift with the springs completely deflated; the system must be filled with air first via the testing device or by running the car partially lifted to avoid improper rubber folding and explosion. Change the set: To ensure vehicle balance and prevent rear tilt, it is always preferable to change the rear springs as a pair (right and left) to ensure uniform sensor response. ❓ Frequently Asked Questions (FAQ): Q: Does it fit the right or left side? A: Yes, the spring is designed to be compatible and installed on both rear sides (Rear Left & Right). Q: Does this spring replace the helper? A: In the ML category, the spring and helper are separate parts; this product is the "airbag" responsible for vehicle height and comfort. Q: Why choose HIGHROAD over cheap parts? A: Because Mercedes is a heavy and sensitive vehicle; cheap parts cause a harsh ride and are prone to rapid venting, which strains the "air compressor" and damages it, leading to greater losses of time and money.
