About Us
FAQ:
Q: Which car models does this front air suspension strut assembly fit?
A: It is specially designed for Mercedes‑Benz W166 ML‑Class/GLE‑Class and X166 GL‑Class/GLS‑Class 2011‑2018, only for vehicles without ADS adaptive damping system, fits both RWD and 4MATIC versions.
Q: Can I install left‑side unit on the right front axle?
A: No, this is strictly side‑specific product. Left air strut only fits front left, right air strut only fits front right. Cross‑installation will cause assembly mismatch, abnormal noise, air leakage and suspension fault code. Please confirm correct side before ordering.
Q: Does this air strut come with ADS sensor?
A: No, this version is without ADS electronic damping sensor. Do not use on vehicles with factory ADS system, otherwise dashboard error code will occur.
Q: What are the common symptoms of failed front air suspension strut?
A: Common symptoms include front end sagging, uneven left‑right ride height, frequent air compressor startup, knocking noise over bumps, air leakage from air spring, poor driving comfort. Timely replacement is recommended when these problems appear.
Q: Do I need calibration after replacement?
A: Yes, professional diagnostic instrument is required to perform air suspension ride‑height calibration after installation, to ensure normal Airmatic system operation.
Q: Can I only replace the air bladder instead of full strut assembly?
A: Theoretically feasible, but we recommend replacing the complete air suspension strut assembly, to guarantee damping performance, sealing reliability and service life.
Q: What quality tests have been performed?
A: Every finished unit undergoes 24‑hour air tightness test (pressure drop ≤0.02MPa) and over 3‑million‑cycle fatigue test before shipment, effectively preventing early‑stage air leakage.
Q: Is it necessary to replace front left and right struts at the same time?
A: You can replace only the damaged side, but simultaneous replacement of both front sides is recommended to achieve symmetric suspension performance and stable driving. Please order left and right separately.
Q: How long is the warranty period?
A: We offer an 18‑month extended warranty. Free replacement is available for genuine product quality issues. Damage caused by improper installation, collision or man‑made destruction is not covered under warranty.
Q: Is this product CE and ISO9001 certified?
A: Yes, this product is CE certified and manufactured under an ISO9001 quality management system, meeting international automotive aftermarket quality standards.
