Hydraulic rear air spring, American manufacturing, Mercedes GL (2016-2019) | HIGHROAD reinforced engineering. Prepare your Mercedes for stability and superior comfort with the rear air spring (Air Spring) from HIGHROAD. This spring is designed with high-density engineering rubber to withstand the heavy weights of luxury SUVs, 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 deteriorate under weight and heat pressure, saving you replacement costs. 🚗 Precise compatibility: Mercedes GL-Class: X166 model (updated 2016-2019). Models: compatible with all engines (GL450, GL500, GL63 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 fibers of the new spring and shorten its lifespan. Cleaning the mounts: the upper and lower spring bases must be thoroughly cleaned of dirt and salts to prevent microscopic holes caused by continuous friction. Weight alert: do not lower the car from the lift with the springs completely empty; the system should be partially filled with air first to avoid improper rubber folding and explosion upon contact with the ground. Pair replacement: to ensure chassis balance and driving stability, always replace the rear springs as a pair (right and left) to ensure uniform sensor response and prevent rear car tilt.
