Product Description
55350‑3M500 (Rear Left) and 55360‑3M500 (Rear Right) are early iterative original matching rear air spring models for Hyundai Equus. They are compatible with the 2011‑2016 Hyundai Equus rear air suspension system and fully interchangeable with 55350‑3M501 / 55360‑3M501. As high-frequency vulnerable parts for Korean flagship luxury sedan air suspension, they are widely used in repair shop maintenance, used car renovation, luxury car finishing and cross-border replacement procurement.
The original Hyundai Equus is equipped with adaptive rear air suspension. After long-term use, the rear air spring bears continuous pressure from rear body weight and trunk load, as well as road vibration and alternating indoor and outdoor temperatures, which easily causes rubber aging & hardening, cord fatigue, sealing port micro-leakage and base sealing failure. Typical faults include rear end sinking after parking, static slow air leakage, uneven left-right vehicle height, rear suspension bump noise, air suspension alarm and abnormal suspension height locking.
When the air spring has structural damage that cannot be completely repaired by repair kits, replacing the full assembly is a long-term and reliable maintenance solution. Manufactured in strict accordance with original factory processes, sealing and pressure parameters, this product perfectly matches the original rear air suspension control system and supports non-destructive in-situ installation without chassis cutting or pipeline modification. After installation, air tightness testing, body height calibration and fault code clearing can fully restore the original air suspension working performance and driving texture.

5. FAQ
Q1: Can 55350‑3M500 and 55360‑3M500 be interchanged left and right?
A: Not interchangeable. 55350‑3M500 corresponds to the rear left side and 55360‑3M500 corresponds to the rear right side. Different base and interface structures will cause assembly failure, incorrect vehicle height and air suspension fault codes if mixed installed.
Q2: Can it be installed on the front suspension?
A: No. The front and rear air springs of Equus have completely different stroke, base and pressure parameters, which are strictly non-universal. Wrong installation is prohibited.
Q3: Is it suitable for mechanically suspended Equus models?
A: No. This product is dedicated to air suspension systems. Mechanical suspension models have no air suspension pipelines, inflation systems or air spring mounting bases, resulting in no compatibility.
Q4: Can 55350‑3M501 and 55360‑3M501 be directly replaced with this OE?
A: Yes. They are original upgraded iterative numbers with identical structure, performance and installation dimensions, plug-and-play interchangeable.
Q5: When is full assembly replacement required?
A: Assembly replacement is recommended when the air spring has rubber cracking & hardening, bladder bulging & deformation, body tearing, continuous slow air leakage or repeated pressure leakage after repair kit maintenance, to solve faults thoroughly at one time.
Q6: Is computer programming required after replacement?
A: No complex programming required. Only air tightness testing, body height calibration and air suspension fault code clearing are needed after installation for normal operation.
Q7: Is it universal for 4.6L and 5.0L Equus?
A: Fully universal. All 2011‑2016 Equus 4.6L and 5.0L air suspension versions share the same rear air spring structural parameters.
