About Us
FAQ:
Q: Which car models does this rear Air Suspension Shock fit? A: It is specially designed for Mercedes‑Benz W223 S‑Class 2021‑2026, for vehicles equipped with factory ADS‑Airmatic system. Compatible with both RWD and AWD versions. Not applicable for ABC hydraulic suspension models.
Q: Can I install left‑side Air Suspension Shock on the right rear axle? A: No, this is strictly side‑specific product. Left Air Suspension Shock only fits rear left, right Air Suspension Shock only fits rear 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 Suspension Shock come with ADS sensor? A: Yes, it is pre‑installed with original‑spec ADS electronic damping sensor. After professional installation and system calibration by Mercedes‑Benz diagnostic tool, no dashboard fault code will occur.
Q: What are the common symptoms of failed rear Air Suspension Shock? A: Common symptoms include rear end sagging, uneven left‑right ride height, frequent air compressor startup, knocking noise over bumps, air leakage from air spring, ADS warning light on dashboard, poor driving comfort. Timely replacement is recommended when these problems appear.
Q: Do I need calibration after replacement? A: Yes, professional Mercedes‑Benz diagnostic instrument is required to perform air suspension ride‑height and ADS system calibration after installation, to ensure normal system operation.
Q: Can I only replace the air bladder instead of full Air Suspension Shock? A: Theoretically feasible, but we recommend replacing the complete Air Suspension Shock, to guarantee damping performance, sensor function and long‑term sealing reliability.
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 rear left and right Air Suspension Shock at the same time? A: You can replace only the damaged side, but simultaneous replacement of both rear 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.
